Change 806241 had a related patch set uploaded (by Clare Ming; author: Clare Ming):

[mediawiki/skins/Vector@master] Show scrollbars in sticky TOC

https://gerrit.wikimedia.org/r/806241

thanks to @Jdrewniak for pinpointing the css that hides the scrollbars -- so went ahead and threw up a quick patch to remove the rule

for QA, I don't have an external mouse nor a windows machine (tho it appears to work in Edge) - hopefully these QA steps will pass fine

@cjming @LGoto @Jdrewniak Scroll bar is visible now, thanks! But before closing this task, in my opinion, the item "Contents" of ToC is the title of this section, and should be viewed permanently, and placed at the top of section, and outside the scrolling area, and should not be scrolled. This is similar to other scrolling area schemes that the title is outside the scrolling area and not scrolling.

Unfortunately it is not visible now on June 17, 2022, 6:26. It was temporarily, it seems that changes has reverted and scroll bar is hidden now (at the time I written on).

thanks @Hooman_Mallahzadeh -- duly noted! I'm going to cc our designer @alexhollender_WMF here about your suggestion.

QA Steps

The scrollbar not show when:

✅ AC1: the TOC is short enough that it doesn't have it's own scroll area
✅ AC2: you are not scrolling

	Firefox - W External Mouse	Firefox - W/O External Mouse	Safari - W External Mouse	Safari - W/O External Mouse
Windows			NA	NA
MacOS

@cjming, @Jdrewniak, I don't know if it matters. But in chrome and safari the scroll bar in the TOC fades as it reaches the bottom, firefox does not.

Chrome	Firefox	Safari

@ovasileva please take a look at T310540#8012892 before you resolve this.

I think it's sufficient to resolve. @alexhollender_WMF - do we want to do a follow-up for T310540#8012892?

Also seeing scroll bar as persistent in Chrome:

that might be dependent on your macOS settings. can you go to System Preferences > General, and check what you've got?
