Bug 150747 – [WebKit2] Gesture Recognition during text editing is often blocked by WKContentView gesture recognition

• Status: NEW
• Component: WebKit2

[Eugene Dudnyk]

- During setup of text editing state the WKContentView's gesture recognizers are not properly configured with dependencies to gesture recognizers of UIWKTextInteractionAssistant.
- Area of recognition of WKContentView's gesture recognizers includes area of edited field as before editing.

This leads to next issues:

- When right after focusing text field perform a double-click on it's text, impossible to show loupe/menu on the cursor/move the cursor. To restore proper editing behavior, another text field should be focused.
- Races occur between WKContentView's long-press gesture recognizers and UIWKTextInteractionAssistant's loupe long press gesture recognizer. Often one of WKContentView's long-press recognizers catches touches prior to loupe recognizer.

Solution could be as follows:
WKContentView should reject for recognizers listed below touches which hit area of edited text field during it's editing, in (gestureRecognizer:shouldRecieveTouch:) delegate callback:
_highlightLongPressGestureRecognizer
_longPressGestureRecognizer
_doubleTapGestureRecognizer
_twoFingerDoubleTapGestureRecognizer
