Inputting text into Image Alt Field causes keyboard to be dismissed after every stroke

[dcalhoun]

Description

When attempting to set alt text for an image with the native mobile editor, the keyboard is dismissed after each character is entered. This makes it incredibly difficult to enter any text beyond a few characters. This issue appears to be present in WPiOS/WPAndroid 17.9, but not the current public release 17.8.

Step-by-step reproduction instructions

1. Launch the editor.
2. Insert and Image block.
3. Tap the settings cog button to open the block settings.
4. Tap the Alt Text field.
5. Attempt to enter a sentence describing the image.

Expected behaviour

The Alt Text field remains focused and the keyboard remains open.

Actual behaviour

The Alt Text field is blurred and the keyboard dismisses after each single character is inputted.
