> After Stage is hidden and shown, the css style is reset to initial value in method `resetToInitialValues()`, which resets the font size of a Control to default font size. This reset results in execution of method `recalculateRelativeSizeProperties()` that was added as part of fix for JDK-8204568. `recalculateRelativeSizeProperties()` uses `getStyleMap()` to get `StyleMap` of the node. In this case `getStyleMap()` returns an incorrect `StyleMap` as the reset is still in progress.
