Thread:VisualEditor/Feedback/Cannot enter change summary, field loses focus

Issue

In the save page dialog, when I try to click the Summary input field, the field immediately loses focus. Instead, focus is put on the article text in the background (I can type there while the dialog is open).

Steps to reproduce:
 * Open any page and make a change through the VisualEditor.
 * Hit save button -> popup opens
 * Click the summary input text field
