Fix the width of some confirmation buttons

[ChrisEdS]

Description

Some buttons need the width property to react correctly.

Motivation and Context

I noticed that some input buttons are too short, actually as long as the text. This often looks unattractive. By setting the width this is fixed.

How Has This Been Tested?

Manual tested
