1716316 - vertical "Conversations" panel is not scrollable without mouse

Status: RESOLVED FIXED

(Thunderbird :: Instant Messaging, defect)

Description

[Jeff McKenna]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.101 Safari/537.36

Steps to reproduce:

• add channels in the Chat (preferably >20 channels so you are required to scroll if you need to see your other channels in your view)
• setup the "Conversations" panel so it is vertical (at least mine is vertical)
• without a mouse, try to click on the vertical scrollbar inside the "Conversations" panel

Actual results:

• the vertical scrollbar inside the "Conversations" panel is stuck, it does not move
• there is no way to scroll to see your other channels (without a mouse)

Expected results:

• clicking on the vertical scrollbar inside the "Conversations" panel should allow you to scroll down the panel to see your other channels

Unfortunately for a while now, if I need to goto one of my channels (that does not fit in my default window view, such as a channel far down the alphabet such as "#zoo-software") I must find a mouse to plug in, to be able to scroll the conversations panel down to my other channels.

Note: in my case these are IRC channels (I am on something like 50 channels)

Just to double check -- this is on macOS on Thunderbird 78? I'm seeing the same issue on Thunderbird 90.0b1.

It seems that two finger scrolling works OK, just not clicking on the scrollbar itself.

Sorry for not including that info: this is on MacOS on Thunderbird 78.11.0

Note that the two-finger-scrolling trick on the Mac's trackpad also does not move the scrollbar (it is there, but stuck/does not move). That trick does work though (as @clokep mentioned) if you try two-finger-scrolling inside the 'Conversations' panel (over the channel names), and not over the scrollbar. I still think that this is a valid issue, as that darn vertical scrollbar should move I feel :)

[Approval Request Comment]
Regression caused by (bug #): ?
User impact if declined: Scrolling chat conversation list is hard
Testing completed (on c-c, etc.): Tested on c-c
Risk to taking this patch (and alternatives if risky): Low, the worst I can see is maybe some weird behavior with selecting/deselecting conversations while scrolling with a mouse.

I realized this patch won't apply to ESR as-is because the file was moved since in c-c. I'll provide an adjusted patch on Monday.
