Details

Steps to reproduce:

  1. Ensure 'accessibility.cache.enabled' is set to true (default)
  2. Browse to https://samples.gwtproject.org/samples/Showcase/Showcase.html
  3. Expand section 'Lists and Menus' in the sidebar on the left side.
  4. Check position of the 'List Box' element using an accessibility tool like inspect.exe by Microsoft

Actual results:

The position given by Firefox accessibility interface is definitely wrong, which can be proved e. g. by capturing a screenshot and checking the position inside an imaging application.

Expected results:

Setting 'accessibility.cache.enabled' to false gives correct position again, but is undesired - should work correctly without having to disable the cache (if possible).

The Bugbug bot thinks this bug should belong to the 'Core::Disability Access APIs' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.
