microsoft / tabster

While testing our product that uses tabster, the Accessibility Insights fast pass failed because the aria-hidden-focus rule is being broken by one of tabster's components. Our component is a Toolbar that uses tabster to enable circular arrow navigation in the toolbar, and the element breaking this rule is a that gets added above and below the children of the toolbar.

According to the rule, elements that have "aria-hidden" = true should not be focusable. The element has aria-hidden=true and tabindex=0, which are contradictory. Looks like this is being set here:

tabster/src/Utils.ts

Line 707 in 3596de9

input.setAttribute(Types.TabsterDummyInputAttributeName, "");

.
