Zoom doesn't work when over text boxes

[acorderob]

Expected Behavior

When using the mouse wheel and the cursor is over a non focused text widget, it should change the zoom level.

Actual Behavior

The wheel does nothing or scrolls the text if there is a scroll bar.

Steps to Reproduce

• Add a node with a text widget, like the "Clip Text Encode (Prompt)"
• Use the mouse wheel while over the text box.

Debug Logs

Not applicable.

Other

The current behavior of scrolling should be kept only if the textbox has the focus.
