I think such kind of fixes should be removed from trunk. Using widgets
without a reference seems to be dirty coding style to me,
which doesn't need  to be supported.

Trying to fixing it would be something like a workaround which isn't
really necessary imho, but creates overhead.

I vote for removing these workarounds.

Just "speaking" out loud my thoughts...
