In my app I have a top bar menu.
Looks like...

It has never been a problem in the past but now in some browsers it is being compressed into a dropdown on the far right of the bar when I open the app like this.

If I click Home then it returns to being across the screen.
I have noticed this before when opening the app on a tablet but never on a desktop browser.
Has anyone seen this before or know of a fix to force it to remain spread across the bar from the left?
I have already tried setting "Runs Across the Entire Screen" in the VP to no avail.
