Labels re-align after rotating a bar graph and then selecting something

Steps to reproduce in bars example:

• select a bar
• rotate the graph
• select another bar

This was introduced after https://codereview.qt-project.org/c/qt/qtgraphs/+/499285 when the 2 lines were removed from the handleXXChanged functions. However, those cannot be added back, as that will result in an endless loop and huge runtime memory usage.
