@IsaDC

I found some other changes that I think are necessary. To help speed things up, I pushed commits for them. Please review them and merge if good.

changed NVDA commands for tests 11 and 12

I removed down arrow from Test 11: Navigate to the next tab in a tab list.
I remove up arrow from Test 12: Navigate to the previous tab in a tab list.
These don't work because all the tabs are on the same line.

Tablist boundary assertion for test 13

For test 13: Navigate forwards to a tab panel

The user is navigating out of the tablist to get to the tabpanel. When arrowing, that should be conveyed. When tabbing, it is optional. I added an assertion for this.

Change assertions for test 14

Test 14: Navigate backwards to a tab panel

• It was requiring name and role and had a priority 2 assertion for tabpanel boundary.
• JAWS and VoiceOver do not convey name, and I don't think it should be required.
• Role is implied in the boundary assertion.
• I changed the boundary to required, removed role, and made name optional.
• For VoiceOver, I removed the shift+tab command
