TitledPane returns unbounded max height when collapsed, causing it to be resized too large in some layout panes

- run application attached: there is TabPane and TitledPane inside of HBox with setAlignment(Pos.BASELINE_CENTER);
- click on TitledPane header (see "Click Here!" label) several times

observe: TitledPane moves down step by step
expected: TitledPane should have only two possible positions: one for collapsed state, one for expanded state
