Perma-characters must be manually deleted on older Android devices #4

To reproduce open this page a Galaxy S3/S5/S7 and type using the default virtual keyboard in the default browser. https://crookedneighbor.github.io/restricted-input-android-formatting-bug/

When deleting the characters, you have to manually delete the spaces. This happens because older Android devices don't emit the backspace key on the keypress event.

We tried a few different approaches to get this working, but ended up deciding to make this a wont-fix and close it.

Pertinent details:

Part of the reason this is happening because Android doesn't report the backspace or delete keys in the key events. event.key === 'Unidentified'
This only happens in older versions of the Android Operating system on the default (non-Google) keyboard
Attempts to fix it just introduced other weird edge cases
