[Reg 5.15 ->6.x] Android: Unable to dismiss "teardrop" cursor from text inputs

Steps to reproduce

1. Launch either the Widgets Gallery Example (https://doc.qt.io/qt-6/qtwidgets-gallery-example.html ) or the Qt Quick Controls - Gallery Example (https://doc.qt.io/qt-6/qtquickcontrols-gallery-example.html )
2. Tap/click into a QLineEdit or TextField and start typing
3. Launch a native Android app that accepts arbitrary text input (e.g. the SMS app)
4. Tap/click into a native Android text field and start typing
5. Compare the behaviours of Steps #2 and #4

Expected outcomes (native Android text field or Qt 5 widgets/controls)
The "teardrop" text cursor handle normally:

• Does not appear when an empty text input field gains focus
• Appears when you tap in the middle of a word/sentence in a text input field
• Disappears when you start typing, or after ~5 seconds of inactivity

Actual outcomes (Qt 6 widgets/controls)
The "teardrop" appears as soon as a text input field gains focus (even if it's empty) and it never disappears.
