reset does not reset kitty keyboard stack in alt screen

[gpanders]

Problem

If an application which uses the alt screen does not reset its kitty keyboard state on exit (usually because the application was killed) then the alt screen retains the kitty keyboard state even after a reset.

Steps to reproduce

The following script demonstrates the issue (note this will make the active terminal window unusable and will need to be force closed):

# enable alt screen
tput smcup

# set kitty keyboard state
printf '\x1b[>29u'

# exit alt screen without clearing kitty keyboard state
tput rmcup

# reset the terminal
reset

# enter alt screen again
tput smcup

Expected behavior

reset should reset the kitty keyboard state of the alt screen as well as the primary screen.

Fixed on paged-terminal, which will be merged shortly. Watch #1584 and when that merges this fix will be on main. Thanks @gpanders
