Landscape " | " does not work

[745m1n]

WARNING: This is a rather ancient project that was originally developed back in 2011 based on the Android 2.3 (Gingerbread) AOSP keyboard. While it still works as-is for many users, it would need some major rewrites to work with newer APIs, and some features such as language switching or popup keys don't work right on modern Android systems. I'm not currently planning on significant updates, and it's possible that it will stop working on modern devices or will no longer be updateable via the Google Play store due to minimum API level requirements. Play Store requires targeting API level 29 (Android 10), while the code was written for API level 9 (Android 2.3) from 2011.

I apologize. I didn't quite understand how to follow the reproduction behaviour.
But, in landscape mode, holding down the backslash(to print | to the screen), does absolutely nothing.
Not a huge issue, atleast for me, due to limited usage of said character. But I just wanted to say "I'm helping". Lol.

I apologize. Immediately after posting...
Appears to be the alt key "selection" distance.
Any other key I hold down when the alt key popup shows is automatically selected by the same press action as holding button(e.g. no movement required to use alt key). I retried this "issue" and after a few finger slips i noticed with the slips it would change. Is this due to some sorta height set issue, or a personal finger position just barely missing selection
