1354238 - Firefox hangs when radiogroup buttons are selected with JAWS Screenreader

Status: RESOLVED WORKSFORME

(Core :: Disability Access APIs, defect, P3)

Description

[u554753]

User Agent 
Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:55.0) Gecko/20100101 Firefox/55.0

Steps to Reproduce:
1. Navigate to http://www.oaa-accessibility.org/example/30/
2. Select elements from the radio group
3. Observe screenreader behavior

Expected Result:
JAWS screenreader reads the output of the radio group the user has chosen on the list.

Actual Result:
Firefox Nightly becomes unresponsive and JAWS reads out information on the selected elements 2 to 5 minutes after the element has been chosen.

This works as intended when e10s is turned off as well as when the screenreader is turned off.

This issue is still reproducible with the following specs when e10s is enabled. However, it's no longer a 2 to 5 minute wait but more of a 45 second to a minute hang.

Firefox Nightly - 57.0a1 
JAWS Version - 18.0.4938

I'm not having any luck hitting perf issues with this test case and the latest version of jaws. 

STR:
1) Navigate to http://www.oaa-accessibility.org/example/30/
2) use the tab key to navigate down to the radio buttons in the test case
3) use up/down arrows to navigate radio buttons

This no longer happens anywhere, can't reproduce with current JAWS and Firefox. Closing. Feel free to reopen if you still encounter this somewhere.
