changing style changes section size if setDefaultSectionSize is set in QTableView

if setDefaultSectionSize() set then changing style does not honors the section size. attached exammple reproduces it:
Run attached example which by defaults starts with "windowsvista" style.
Then press button "windows" or "Fusion" button and the size of the row remains unchanged.
Now press"Fusion" again and then press button "new table". The size of rows has
changed. Then press button "windows" and the size is still the same, only the
style of table has changed. Next press "new table" again and now the rows size
has changed again ... .

Not reproducible with Qt5.11
