Due to various CSS transitions/animations/transforms, checking the visibility of elements is not always correct. This leads to random fails.


Proposed resolution

  1. Additional conditions for checking visibility, like #2848177-14: More \Drupal\Tests\outside_in\FunctionalJavascript\OutsideInBlockFormTest random fails
  2. Disable these CSS rules for testing, like #2901626-5: CSS animations cause \Drupal\Tests\outside_in\FunctionalJavascript\OutsideInBlockFormTest random fails
  3. Finding another solution (maybe wait to #2775653: [PP-2] JavascriptTests with webDriver)

Remaining tasks

User interface changes

API changes

Data model changes
