SearchBar keeps a TextFieldValue so that the cursor ends up behind text that was
changed from the outside (a search started by typing on a physical keyboard, or
a reset search). That value was updated during composition, which is an
anti-pattern: the value read earlier in the same composition is what gets drawn,
so the write only schedules another recomposition pass of the search bar - and
it can be dropped entirely if the composition does not complete.
Do the same update in a SideEffect, after the composition. No behaviour change
for the user.
