Subject: [PATCH] QFontComboBox: inform accessibility about model reset when
 filter changes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Signals are blocked explicitly, so the modelReset signal that would
normally make the view update the accessibility framework does not work.
Update accessibility explicitly.

Fixes: QTBUG-114423
