I believe this is intended behavior. You should use a regular interval
timer if you want repeating executions that do not depend upon Emacs
entering the idle state. Not sure why you think this worked differently in
the recent past.

"Emacs becomes *idle* when it starts waiting for user input (unless it
waits for input with a timeout, see Reading One Event
<https://www.gnu.org/software/emacs/manual/html_node/elisp/Reading-One-Event.html>),
and it remains idle until the user provides some input. If a timer is set
for five seconds of idleness, it runs approximately five seconds after
Emacs first becomes idle. Even if repeat is non-nil, this timer will not
run again as long as Emacs remains idle, because the duration of idleness
will continue to increase and will not go down to five seconds again."
