When Orca has "Speak object under mouse" enabled, it tries to get the text range extents for any object that implements the AtkText interface and gets a bit confused by our AtkText stub implementation that merely returns null for `get_text`. Removing the stub implementation helps to avoid the issue that Orca would try to call `atk_text_get_range_extents()` with `start_offset=0` and `end_offset=0`: > Atk-CRITICAL **: atk_text_get_range_extents: assertion 'start_offset >= 0 && start_offset < end_offset' failed

It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption to this rule, contact Hixie on the #hackers channel in Chat (don't just cc him here, he won't see it! He's on Discord!). If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. |
