When having the cursor in a text object, entering the Check Spelling feature,
closing it, the pointer tells you you are in the text object.
When clicking the text-object Impress only  lets you move the text object, not
enter it.

Repro:
1. Click yourself into a text object on the screen so that the pointer starts
blinking.
2. Enter Spell Checking (F7)
3. Just close the Spell Checking
4. Try to click somewhere in the text object again. You will not be able to
enter it, despite the cursor being present. This behavior stops when clicking
outside the object, or when clicking and holding.
