Bug 199430 – REGRESSION (iOS 13): Tapping an element with a click event handler no longer clears the selection

• Status: RESOLVED
• Resolution: FIXED
• Component: HTML Editing

[Wenson Hsieh]

This makes it nearly impossible to truly dismiss a text selection on a New York Times article, Google search results page, and other big websites. I wrote “truly dismiss” because while it looks like the UIKit selection view disappears upon tapping, the DOM selection remains the same.

To reproduce:

1. Go to any New York Times article.
2. Make a text selection.
3. Try to dismiss the text selection by tapping on some other text. Notice that the blue tinted selection view disappears.
4. Open Web Inspector and type “getSelection().toString()”.

Expected: Empty string.
Observed: The originally selected text.
