Single-tap not working in tab widget action

I can't get an action to run on a single tap (click) in a tab widget. Double-tap works fine.

I'm assuming this has something to do with needing to pass the tap action through from the widget, which is already capturing the click event to switch the content. But I can't figure out how I might do that.

I'm trying to update a page state variable based on the current tab, which is the need for the action.

Any ideas?

Thank you!
