This is a bug report just for tracking its status in Debian.





Steps to reproduce:

Switch between tabs with control-page up / down


Actual results:

Events
interface=org.a11y.atspi.Event.Object; member=StateChanged string "selected"
for the newly selected tab are not always emitted: they get emitted when using control-pagedown, except when arriving on the last tab. Conversely, they never get emitted when using control-pageup, except when arriving on the first tab.


Expected results:

Events
interface=org.a11y.atspi.Event.Object; member=StateChanged string "selected"
for the newly selected tab should always be emitted
