1204352 - chat view sometimes doesn't scroll to bottom if messages get added

Status: RESOLVED WORKSFORME

(Hello (Loop) :: Client, defect, P3)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Firefox Nightly 43.0a1 20150913 on Windows 8.1

The chat view sometimes doesn't scroll to the bottom if new messages get added.

Steps to reproduce:
1. Start a conversion.
2. In the chat windows, send messages like "test1", "test2", ...
Actual result: The view will get stuck and messages be added to hidden area not shown. (If there was a scrollbar, it required me not more than 3 messages to force this behavior.)

[Tracking Requested - why for this release]:
A) Seems to be a regression.
B) User can miss new messages.

Tracking since this looks like a recent regression, major for some users of this feature.

Sebastian, are you happening to scroll the text view at all? If you scroll the view, you'll need to scroll back down to the bottom for you to see the messages.

There should also be sounds for the fact a new message has come in, so you should be notified in some manner at least.

I don't think this is a regression - we haven't touched this functionality since it landed. So if you are able to provide a regression range, that would be useful.

I wasn't able to reproduce ~1 week ago and now fail to get a stable chat connection with Nightly and FxOS master > RESOLVED WORKSFORME.

Looks like we don't need to track this since it's WFM.
