“The clickable issue is still not fixed. Sometimes text that isn’t clickable shows up as clickable. Or it’s the reverse -- in the Gride app, clickable text for requesting a ride doesn’t click with chrome.

Reduces the number of items that are announced as clickable by Jaws or NVDA.

An element gets the click action when there is an anchor or an element with a click listener in its ancestry chain. For the latter case this change exposes a different action name, "click_ancestor", on Windows to stop Windows screen readers unnecessarily announcing many items as clickable.

Stops ignoring clickable elements.

With the addition of |AXActionVerb::ClickAncestor| there were some situations when the click handler was on an element that was ignored. When the AT tried to go up the ancestry chain to find the clickable element, it failed.

We did whatever we could from our side. We only expose the clickable action on items that have a click handler directly placed on them. We made a change excluding any click handlers that are found on ancestors.
