    Description

      The very simple testcase attached (QTabWidget, 2 tabs, the first one with a very short title, the second one with a longer title, and setCurrentIndex(1) before show) shows only one tab instead of two. This worked in 6.5.0 and before.

      The regression comes from commit e851d4c06154bf02b23030ff1f7024a8b9edf874 "QTabBar: don't scroll when laying out the tabs"

      If I revert aef2486775497903a1d5 and e851d4c06154bf02 in my v6.5.1 build, it works again.
