The "On object clicked" condition never works on any of the built-in HTML elements (Button, File chooser, List, Progress bar, Slider bar, Text imput, etc.)
And the "Cursor is over object" condition only works sometimes on such HTML elements.
It's always been this way and I was told intentionally so. Maybe the mouse only detects <canvas> objects. The button has its own click condition you can use though.

However, strangely, the "Cursor is over object" condition works sometimes on the built-in HTML elements. This made me think that maybe it is a bug that prevents this condition from always working on these elements.
