[VO] slider "increment" feature reads the wrong aria-valuetext #36

Open jessegreenberg opened 7 years ago

jessegreenberg commented 7 years ago

When incrementing a slider with value-text through the "VO + spacebar" keys, sometimes the old aria-value text is read out. See the following JSFiddle example to reproduce the bug.

The following issue has a bunch of documentation on attempting to isolate the cause, but we have determined that this is a VoiceOver bug with the "increment" feature.

I am unable to get this bug to happen in the JSFiddle, though I am still able to observe in the latest deployed version of john-travoltage.

This one has been more elusive, I spent some trying trying to reproduce and cannot get it to happen in any JSFiddle. Looking more likely that this is a bug in the sim.

Or maybe performance if VO is "pulling" the value for aria-valuetext after an input or change before it is updated in the accessibility tree?.

I just verified on 6/18/18 that this is still a bug.
