Magento2: Magento Admin pages not fully loading and rendering when opened in the background

[orbitrod]

Preconditions

1. Magento Version 2.2.3
2. Chrome Version 66.0.3359.181 (Official Build) (64-bit)

Steps to reproduce

1. Login to Magento Admin
2. Navigate to Products
3. Open multiple edit product links in new tabs
4. Wait a few seconds for all loading indicators to stop spinning for new tabs
5. Switch to new tabs that were opened

Expected result

1. The new pages should fully load and render in the background.
2. When switching to the new tab the page should be fully loaded and rendered.

Actual result

1. When switching to the new tabs, the pages are not ready to go. They are not fully loaded and require a little more time for the product fields and information to populate.

I have done some more testing and I believe that this behavior might be exclusive to Chrome. Firefox and Edge do not behave this way. They fully load pages in the background.

Does anyone know why Chrome might be behaving this way vs the other browsers?

[orbitrod]

Does anyone have any advice on how I can get these pages to load in the background?

Awesome, thank you for the update.

@orbitrod I have found the same issue on Firefox too. I believe this is not browser specific It must be due to Magento 2 UI js behavior. I will work on it to find the exact reason behind it.

Firefox clearly behaves the same. (Magento 2.3.3)
I'm annoyed by this ever since I switched from Magento 1.9 to Magento 2.1 (and later 2.2 and 2.3).

"Assignees: No one assigned" after 1.5 years?

[orbitrod]

@MarcusWolschon Glad to see you on this issue. If we can get more people to confirm this problem, we might be able to get the attention of the developers to issue a fix.

This poor design or a bug is still happening in 2.3.5-p1. Even more time is wasted when you do tracking on Sales > Orders page.

I will give you an example.

1. Open an order to enter tracking information, once done click on Back button, page starts loading
2. Switch to another tab to, for example, get tracking for another order
3. Go make a coffee and get back after 15 minutes
4. Open the tab showing Orders... it hasn't loaded at all!!!!

I am not sure how this "feature" is still in Magento 2, after 4 years. Small businesses running M2 do not have unlimited amount of time. Why would you stop loading pages when a tab is switched? Those 5-7 seconds it takes to load the Order page I can do "other" stuff. Those seconds add up when you do 10 hrs a day every in Magento 2. Countless hours are wasted waiting for page to load.

just for the search folks:

you just have to add an template to the pages or global for every adminhtml page with "$(window).trigger('blur');".

tested with magento 2.3

_Custom/Module/view/adminhtml/layout/default.xml_

<?xml version="1.0"?>
<layout xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/layout_generic.xsd">
    <referenceContainer name="content">
        <block class="Magento\Backend\Block\Template" name="alway.blur" template="Custom_Module::blur.phtml"/>
    </referenceContainer>
</layout>

_Custom/Module/view/adminhtml/templates/blur.phtml_

<script type="text/javascript">
    require([
        'jquery'
    ], function ($) {
        window.setTimeout(function() {
            $(window).trigger('blur');
        }, 1000)
    });
</script>

Yes, this is really annoying. Think of all the power users that have to work with magento every day.
I am just developing and I am already getting nervous twitches whenever I see a spinner on the screen.
