Picker behavior change with iOS 14?

I have a couple apps that use text pickers and I've noticed a text alignment problem where left-aligned text is shoved so far left that the leftmost character or two gets cut off. The problem started with iOS 14 and continues in iOS 15. I have a kludge fix that adds two spaces to the beginning of the text string to be displayed in the picker. It works great, but I'd like to better understand what's going on.

I've noticed that it's widely known that date pickers behave differently as of iOS 14. I haven't seen anything about text pickers. Does anyone know of a change that might effect text alignment in text pickers as of iOS 14?

The details of my issue are available at stack overflow.
