`wl-copy -c` hangs indefinitely around suspension/unsuspension

[hcsch]

Seems like a similar issue to #168 where I originally posted #168 (comment).

KeePassXC seems to clear the clipboard somewhere around a suspend/unsuspend of the OS and the wl-copy -c process started for this hangs indefinitely on

wl-clipboard/src/wl-copy.c

Line 321 in 3eb912c

while (wl_display_dispatch(wl_display) >= 0);

See keepassxreboot/keepassxc#12267 for the original KeePassXC issue.
