Bug description
A single press on the numberpad backspace key causes the computer to
think the key is held down. The continuous backspace only stops when
another key is pressed. From playing around with a CLI program called
evtest, it seems the computer sets the key value to 1 on press but
doesn't set it to 0 on release. For other keys, a return to 0 is the
normal behavior. Evtest will repeatedly report a value of 2 if a key is
pressed and held, and it does this correctly with the numberpad
backspace. However, a single press on the numberpad backspace and then a
single press with the regular backspace shows a value of 2 for the
second key even though the first was not held.
The standard backspace key behaves as normal.
Steps to reproduce
Open a text file and populate it with text
Press the numberpad backspace
watch the cursor eat the text without your help
press any other key to stop the madness
Expected behavior
Should behave the same as the ordinary backspace
Additional information
