Scrolling: Ability to scrollback can get stuck

[ara4n]

In an encrypted room, it's possible for scrollback to stop loading, despite you not being at the beginning of the room. A workaround is to click on the timestamp of a message towards the top of your timeline in order to permalink it, which causes it start back-paginating again. However, it obviously shouldn't stop refusing to scrollback in the first place.

I don't think I am able to repro. Do you have a repro case? Have you seen this before or is this a regression?

[ara4n]

i've seen it a few times before; i think it is a regression (but could have regressed months ago). will try to repro.

video of me reproing it. i'm afraid it's in an internal room, so i've had to crop the video comically, but suffice it to say that i'm leaning on page-up in order to rapidly backpaginate, and then when it gets stopped, i have to click on the permalink for the first message in the room for it to let me continue backpaginating again. will rageshake too.

n.b. there is no spinner when it gets stuck. you just have a big hunk of vertical blank margin which you can't scroll beyond.

I wonder, this only happens in this room or also other ones? I attempted to repro in a few rooms but I didn't manage to do it
