Problem
The suggestions extension will continue to react to selection changes even when the editable is "readonly", which can lead to it showing a pop-up for text that start with the trigger character. This was discovered in #2680.

Fix
We need to ensure we don't attempt to detect a suggestion at the current selection when isEditable is false. The attached commit will fail-fast and cleanup any active suggestion state. Demo:
