flutter web textfield is hard to open copy and paste menu with double-tap on ios phone

### Steps to reproduce

On Flutter Web for Android, after long-pressing a TextField, the paste functionality appears correctly. However, on Flutter Web for iOS, users typically double-tap to bring up the paste menu. When double-tapping, the menu briefly appears but quickly disappears. If the TextField contains text, it gets fully selected. It seems that the "select all" action overrides the paste menu. Long-pressing, however, works as expected and correctly opens the paste functionality.

### Expected results

When double-tapping on ios web, shows the copy and paste menu.

### Actual results

When double-tapping, the menu briefly appears but quickly disappears.
