Double text in TextInput box after right clicking in it

After right clicking in a TextInput box, characters are duplicated when typing. I tested with QML Media Player example and "Qt Quick Layouts" example.

1. Run QML Media Player example with Multithreaded WASM
2. Open File -> URL
3. Right click in URL text box and start typing

Expected behavior:
3. One character is displayed for each key press

Actual behavior:
3. Two characters are displayed each time a key is pressed

Environment:

• Tested with Chrome and Firefox
• Windows 11
• Emscripten 3.1.37

Not reproducible with 6.6.1
