Hi!
I was able to reproduce this issue on latest Nightly version 95,0a1 (2021-10-26)(64-bit), Beta 94.0b10 and Firefox Release 93.0 on Windows 10.
I've used http://www.sharonminsuk.com/code/storage-test.html and I've followed the steps shown on the video attached.
I'll change flags and set a component to have a starting point for this. Please feel free to change it if you consider one more appropriate.
