1. Version of Adobe InDesign, InCopy or InDesign Server
   17.0.1 x64

2. Steps to reproduce the issues
   Link some textboxes, fill boxes with text, and apply a paragraph border to all (or a large amount) of the text.

3. Expected result
   If "Display Border if Paragraph Splits Across Frames/Columns" is unchecked, there should be no paragraph border from one column to the next regardless of whether or not a paragraph concludes at the bottom of the textbox.

4. Actual result
   If a paragraph begins on one textbox and concludes on the next textbox, everything works as it should. However, if a paragraph finishes at the end of a textbox, it will display a line border at the bottom regardless of whether or not the next paragraph in the next textbox has the same border settings.

5. Test file, screenshot, video or GIF capturing the issue (optional)
   Left, this textbox has a border, even though the following paragraph has the same settings and should therefore merge. Right, the textbox displays correctly, because the paragraph continues from one box to the next.

There is also a bug within this bug, which I mentioned here https://community.adobe.com/t5/indesign-discussions/don-t-display-border-if-consecutive-borders-splits-accross-frames-columns/m-p/13326155#M501200 but let's fix the bug first, and fix the bug in the bug later.
