Simple-tab-groups: Clicking on Open group in new window reloads all tabs for this group

[lafiel]

Hi there,

To Reproduce
Steps to reproduce the behavior:

1. Click on the STG in Firefox
2. Right click on the group and select "Open group in new window"

Expected behavior
Before you could be sure "open groups in new window" would load the tabs from cache (or perhaps only the on the tabs you clicked on) and not refresh _all_ of them from the internet.
If you have 20 tabs it slows things down and uses more RAM than necessary.

**Desktop

• Linux 5.3.8-3
• Firefox version: 70.0.1
• Simple Tab Groups version: 4.3.2

I think that's a temporary fix for bug #456 and related.

Yes, this is a temporary fix and inconvenience...
Need to wait when they fix
https://bugzilla.mozilla.org/show_bug.cgi?id=1580879
and the code that does the reloading of the tabs will stop working automatically
