Report "Relatively obscure app crash when pressing buttons too quickly"

[K1rakishou]

UUID: 47281b42bc1da4b7620876733a0c10d2
Build flavor: stable
Version name: v4.12.0
OS info: Android 10, sdk version: 29
Report description: When viewing images in Gallery mode, if you tap the Jump to Post arrow, then quickly tap the Image Gallery button (which replaces the Jump to Post arrow, as the app is going back to post view mode), before the animation finishes, the app will hang. Hitting the Image Gallery butting again will subsequently crash the app.

This is not an intrusive crash, and is easily avoidable.

I remember some similar crash was fixed recently but maybe this is another way to reproduce it.
