Can't paste into empty text field on Android

If a text field has some text in it, you can tap-and-hold to show the standard Android context menu to Cut/Copy/Paste the selected text.

However, if the text field is empty, tap-and-hold does not show the context menu.

The attached qml example has two text field, one with some initial text, one empty with just place-holder text. To demonstrate the problem, tap-and-hold in the top control to select some of the text, then tap-and-hold in the empty control. No menu is shown in the empty control. If you type a few characters in the empty control, then tap-and-hold, the menu is shown.
