Scratch-www: load more button scrolls the page down

[jeffalo]

when pressing the load more button, the page is unexpectedly scrolled down.

this seems to happen everywhere with a load more button

Steps to Reproduce

1. find a place with a load more button. (eg explore)
2. press
3. you are scrolled down

Operating System and Browser

Windows 10 1909 Chrome 84.0.4147.105

i don't know if this is a feature but it doesn't seem like its the expected outcome of the load more button.

I can reproduce on the same browser and OS. This only started happening recently (maybe the past 2 weeks?). Before that, the load more button would load the comments but wouldn't scroll down the page automatically.

This is probably Chrome bug; cannot repro on Firefox 79

Cannot repro on older versions of Chrome. I agree with @apple502j, this does look like a Chrome bug. But having said that, Scratch should try to fix this.

This can be fixed by setting overflow-anchor: none. I made a userstyle that fixes it.

[mxmou]

It is a recent update to Chrome but I believe it's intentional.

@benjiwheeler Can you make this help wanted?

This happens very often with me and I use Chrome all the time, so I'm pretty sure this isn't a Scratch issue in general. This bug is very annoying because I enjoy reading comments on famous projects and famous user's profiles to find inappropriate ones and just see all of the memes and compliment, and half of the time I can't read anything properly since this gets in my way. It would be helpful if this gets fixed soon.

@mxmou Is there any way you can make a pull request with your userscript so it can get fixed easily? I don't think I'll be using that userscript on Tampermonkey until I'm sure this won't get implemented any time soon.

@Nambaseking01 issues should be marked with help wanted before pull requests are submitted.

[mxmou]

@Nambaseking01 I could make a PR but as @Accio1 said this isn't marked help wanted.

[Nambaseking01]

@Accio1 @mxmou Ah OK, thanks for the confirmation. I'm new to this repository, I've only recently been posting on issues here and searching for bugs on the websites.

[benjiwheeler]

@mxmou I'm going to check this with the design team to confirm that we want to change this -- if so, I'll mark it help wanted.

[benjiwheeler]

@mxmou Yes, we would like the fix! Please do submit your PR when you get the chance, and please @ me.

I believe everyone is on the same page, but just to confirm the design behavior:

The current behavior is not desired: jumping to the end of the newly loaded comments after clicking the "Load More".

Instead, after clicking the "Load More" button, the comments should load but the scroll position should remain unaffected. Assuming the comment viewer does not scroll the page while comments are loading, this will result in same scroll position being the same as when the "Load More" button was clicked. This behavior ensures the comment viewer maintains their position in comments. The viewer can scroll down reading the newly loaded comments and click "Load More" again to load another batch of comments with the same behavior.
