This PR fixes a long standing issue where the `Tooltip` will always wait one second until it appears the very first time, even if the `-fx-show-delay` was set to another value.
The culprit is, that the `cssForced` flag is not inside `Tooltip`, but inside the `TooltipBehvaiour`. So the very first `Tooltip` gets processed correctly, but after no `Tooltip` will be processed by CSS before showing, resulting in the set `-fx-show-delay` to not be applied immediately. Added a bunch of headful tests for the behaviour since there were none before. ------------- Commit messages: - JDK-8296387: [Tooltip, CSS] -fx-show-delay is only applied to the first tooltip that is shown before it is displayed Changes: https://git.openjdk.org/jfx/pull/1394/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=1394&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8296387 Stats: 300 lines in 3 files changed: 277 ins; 5 del; 18 mod Patch: https://git.openjdk.org/jfx/pull/1394.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/1394/head:pull/1394 PR: https://git.openjdk.org/jfx/pull/1394
