The scroll to the bottom shortcut dissapear when scrolling upwards too much...

[Grabber]

Describe the bug The scroll to the bottom shortcut dissapear when scrolling upwards too much and only reapears if you scroll downwards again, by a little. As on WA, it could be always visible. The current behaviour seems not 100% intuitive, at least my mom couldn't not figure it out without an explanation ;)

To Reproduce Steps to reproduce the behavior:

1. scroll upwards by a lot;
2. the scrolling to the bottom shortcut will disapear;
3. it will appear again if you start scrolling down again;

[or-else]

It's a matter of personal preferences.
