mit-clx/portable-clx use a macro ENCODE-TYPE to convert the number.
See SET-DRAWABLE-X in attributes.lisp.

A typical scenario is using Gmail web interface in chromium.  When I
clicked "Delete all spam messages now" or "Empty Trash now", these
links raised browser built-in dialogs.  After closing the dialogs,
this bug *often* happened.

But since Gmail has replaced browser built-in dialogs with html
dialogs, I can't reproduce it anymore.

I recorded a video [1] which shows how Conkeror caused this bug (no
.clfswmrc and .conkerorrc during recording).
