Cursor support in Swift5.3

[rubengarciam]

Describe the bug
Cursor support in Swift5.3 is not there yet, definitely not on par with UIKit.

Using the trackpad behaves erratically too. I need to double-tap vs the expected single-tap and sometimes the button view disappears (?)

Screenshots
Attached are some screenshots that show how it compares:

• Default navigation button
• Toolbar button with padding
• Toolbar button without padding
