WalrusIRC scrolling bug on Android

I noticed some issue on Android with WalrusIRC scrolling but I don't know when it started happening:

If you scroll up all the time, then it's fine, but if you scroll down, you instantly jump at the very bottom, then a second time if you scroll up immediately afterwards.

This can be annoying for reading logs.

Can't reproduce in chrome, that's odd. It might be related to images loading since that triggers scrolls.

Bump: @lazydogP reports that the same problem is happening on Firefox in Android. In Chrome Android I still have the same issue.

The aforementioned bug only happens in the fullscreen WalrusIRC client, not the embedded shoutbox.

* DJ Omnimaga pokes @Juju and @Streetwalrus to fix and glares at the topic date <_<

BTW, here's the environment.
Firefox Beta 49.0b11
720*1280 display resolution (320 DPI)
Hope it will be useful.

It's caused by the "window" changing size as the navbar hides or shows up. If I were to remove it then it wouldn't scroll down upon rotating the phone. May be a good idea to check whether it's already scrolled all the way down first.

Remind me on Thursday please.

I wonder how many people in the TI community have their phones set to automatically rotate the display, though... in my case I found that Android feature to be by far the most annoying thing in existence >.<

Same. :P But it's a thing to consider, it's also problematic on desktop when resizing the window.

DJ Omnimaga

Now that you mention desktop, I recently had that issue where WalrusIRC scrolled down at the bottom on every message, but then refreshing the page fixed it.

This also occurs on Safari in iOS. One thing to note is that it only happens in full screen mode.

Welp, looks like there is no easy way to fix it without breaking resize handling. :/ I need to look into it more.

Didn' Safari on iOS as well as every other iOS browser also fail to show the textarea and send buttons in shoutbox mode?
