Icon is rendered incorrectly in the header

[botkero]

Hello,
I would like to integrate icons into the sidebar, and don't quite know whether this should theoretically be an insider feature only. Some things work though, but I noticed a bug if you don't be just “have one page” but have a folder structure. The section header does not render the icon on the page correctly. It is difficult to explain. That's why I put in two images and a minimal configuration.

When I'm on the top of the page:
on_top_of_the_page

When I scroll a bit down:
scrolling_bit_down

Here the minimal reproduction:

Ok, so I could reproduce this using Firefox and 9.4.8+insiders.4.43.0, see below. This occurs when scrolling down on the index page for the "More" section (only, as far as I can see):

Could you please do us the favour and have a look trough the discussions and issues to see if this has been reported before? If not, could you create an issue with a minimal reproduction - same as what you posted here but using the instructions on creating a minimal reproduction. It is important to remove as many other settings as possible while still reproducing the issue. That rules out any more complex interactions between settings - or flags them up.

Yes, thank you for the confirmation. I'll try to remove all other settings that are not necessary. Could take a while.

Just for keeping track of things: it's an upstream issue, as already mentioned in #6315.

Sorry, I was looking for icons and couldn't find the upstream issue. If I had searched for emojis, I might have found it sooner.

No worries, I agree that this was quite a little harder to find.
