Content of the OverlayPane(Slider?) has wrong horizontal position
To trigger the bug, reproduce these steps:
- Launch sdm-modeler, branch develop, commit e2a55733aa71ec6054a5d0f929b9da0551afd683 December 2nd 2019, linking against dtk-widgets, branch develop, commit 1260e620 December 2nd 2019
- In Workspace 1, go to submenu Parameters, then to Workspace 2, then click back, then to Workspace 1, then to submenu Parameters.
- Expected behaviour: the submenu Parameters is correctly displayed. Observed behaviour: I can see half of the previous menu (workspace 1) and half of the current menu (parameters). The split is vertical <-> the horizontal position is not correct.
