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.

requestAnimationFrame was not sufficient here. It happened too early. The requested animation frame was returned before this control's final sizing-layout happened. I tested with `rAF`, `startJob`, and `asyncMethod`. `asyncMethod` seemed to be the most concise, while still achieving the desired result.
