[Acc] Button tooltip doesn't show up on tab\

[setaskin]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.60.0 (user setup)
• OS Version: Windows 10

Steps to Reproduce:

1. Navigate through VS Code Search tab and tab through all the buttons . ( refresh , clear search results , etc. ) ( Search tab is just an example I can see the same behavior in all buttons)

Expected : On the tab navigation to each of the button, the tooltip should be displayed. On escape the tooltip should be dismissed. Keyboard users will not know what is the use of the button through the icon for the button.

Actual : User cannot see the tooltip when they tab into a button. They can only see the tooltip when they hover over.

@isidorn , Hey, I search to see if there is something already open but couldn't find it. I hope it is not a duplicate.

Dup of #52016
Reasons why we are not changing this still hold which I mentioned here

Leaving this open for tracking purposes.

Removing accessibility-sla label because we got confirmation from the testing team that this can be moved to Severity 3.
Reasoning why this is Severity 3 can be found here

Hi @isidorn , we met the same issue. In our Teams Toolkit extension, we have several buttons on tree items. When user tab to the buttons with keyboard, tooltip will not show:

Accessibility team has raised a Sev2 bug to us for this issue. Is it possible to fix this?

This can be closed when #154364 happens

Ben has adopted the custom hover in our base widgets, so this may now be easier than before?

Kai mentioned I should consider adding a delay like we have for mouse hovers here. I need to see if this is acceptable by accessibility standards.

[meganrogge]

AFAICT, the WAI-ARIA guidelines do not specify that there cannot be a delay.

@benibenj it seems like this already works thanks to your changes

button.mov

When I tested on native Windows explorer, I saw a delay even when using keyboard, so it seems the same delay should apply for keyboard and mouse.

[benibenj]

Currently the mouse and keyboard delays are exactly the same which is what we want. We do not have delays where we support instant hover such as navigating between action items on a toolbar/actionbar.

FYI: pressing ESC closes the hover

@benibenj awesome work!
