Slow performance on mobile Firefox

I noticed that the application is at times slow on mobile Firefox, especially short after opening the application. I can replicate the issue for example in Chrome when setting CPU throttle 6x. Pressing Enter on an empty line can take 500ms, Arrow up or down (just moving the cursor) can take 300ms sometimes. Evaluation of the whole sheet that I tested with takes 1200ms, but that only happens after making a change in an expression. I just wouldn't expect that moving around the cursor would be so heavy 🤔 . I don't see a performance issue on Mobile Chrome though.


Not something I'll be looking in soon but just as a reminder.
