dooh me they were the same, thanks Sri

I referenced this issue in #9809 but that's wrong. #9809 solved #8429. I referenced the wrong issue by mistake. Re-opening

[LaurenWags]

@cezaraugusto - noticing that the tabs from the first tab set don't have their favicon resized the way the tabs from the other tab sets do. Could you take a look?

[cezaraugusto]

could you share your STR? I think I know what's happening

[LaurenWags]

just tried to confirm my steps were the same as from the description, but now i'm seeing this :(

@cezaraugusto is this expected? (the tabs are too small to display a favicon?)

[LaurenWags]

Reopening per #9779 (comment) - I no longer see a tab favicon when I set the tab count to 100.

[cezaraugusto]

@LaurenWags depending on your window size a tab with no icons is expected. However, #9779 (comment) is not. I'm not able to reproduce following @srirambv STR:

I have a guess-fix but hard to know it's working without reproducing. Let me know if there's something I'm missing

^ sorry for the bad GIF quality

[cezaraugusto]

also, could you tell me which version rev are you on? I'm on de5970f

[LaurenWags]

So to recap some slack convos - can no longer repro #9779 (comment) I only see #9779 (comment) which makes sense as discussed because at some point the tabs are too small to display a favicon.

However, (maybe this needs a new issue?) If I have a full screen window, and 100 tabs, no favicons. But, if I restart Brave the favicons do display:

This is using:

@LaurenWags what happens in that state you mentioned in #9779 (comment) if you keep changing the number of tabs per tab set? does at that window size the icons are shown or just keep the same?

per your screenshot, you reached a point where icons should be visible, but if you have resized the window before by increasing the width, it might not be updated at the right time given the number of tabs.

The time for icons to update based on tab size is variable and depends on how fast you resize, for slow resizing, components take more time to update given the operation cost in CPU. Fast resizes usually update instantly. An app restart as you did force the update which is why you see the icons.

If changing tab set size with the window at the same width do update the icons IMO we can close this. The delay of updating icons on window resize is variable and while not really a bug, could be improved over time and best take would be opening another issue.

Thanks @cezaraugusto and will open up something separate 😄
