BHV-15180: Allow the components to render before measuring them

... so the `titleBelow` and `subTitleBelow` get sized correctly.

Updated the adjustTitleWidth method to use a less costly measurement method.

`offsetWidth` is sufficient and works just fine for these purposes, which I had tested and used initiall. The getBounds() seemed like a better abstracted process, even though it generates an anonymous object and references 4 properties instead of just the one.
