Widget Components not interactive on mobile

I can’t get button widget components to be clickable on mobile devices or in the editor when “Use Mouse for Touch” is enabled.

I’ve created a sample project to show the problem:

I find the problem on a blank project after adding a widget component, setting the user widget to a button binded to a print string node. This happens when the WC is in screen or world mode.

Please help me.
