I was actually quite surprised to find that abbreviations don't work if you wait 'updatetime' milliseconds between starting and ending the abbreviation, triggering the CursorHoldI event. That could be due to specific events firing, I don't really know, but it is not documented anywhere I could find.

This mapping seems to do what you want, as a workaround:

inoremap <F4> <C-C>ciW<C-R>-<C-]>

<C-C> is used to end insert mode without triggering events or abbreviations, ciW then deletes the unexpanded abbreviation and enters insert mode, <C-R>- inserts that deleted text, and then <C-]> expands the abbreviation.
