Hello all,

Problem: In iOS 14.5, dynamically setting pointer-events: none on a parent div still lets through touch events from text child.

Scenario:
1. Imagine you have a parent div that contains a child div with text.
2. In a touchend handler on the parent, you set pointer-events: none to the parent so it stops accepting further touch events
3. Tapping on the text of a child div still lets through touch events to the parent which is not desireable and which wasn't the case in iOS 14.4
4. Repainting the text child "fixes" this and correctly stops the child from letting through touch events.
