Version 21.2

I saw this error in earlier versions of InDesign, but it was later fixed. Now it appears to have returned. I copied text into a text frame and the intelligent text flow created additional pages and frames to fit the text. While scrolling through the document, I noticed that the text in some frames (fewer than 5%) is partially positioned above the top of the frame (see image). To fix this, I open the Text Frame Options, change the vertical justification, and then change it back to the original setting (Top). The frame then fits the text correctly.
