patch 9.1.0222: missing 'below' virt text if truncation precedes after/right text Commit: https://github.com/vim/vim/commit/fe0a76b2bca12b13982ad66bafadc0d6c1681d00 Author: Dylan Thacker-Smith <dylan.ah.smith@gmail.com> Date: Thu Mar 28 11:47:32 2024 +0100 patch 9.1.0222: missing 'below' virt text if truncation precedes after/right text Problem: When a line is truncated just before 'after'/'right' virtual text and the line also has 'below' virtual text, then the 'below' virtual text would not be displayed, depending on the order these text properties were added. Solution: In the loop to make text properties active, skip instead of break for 'after'/'right' virtual text properties that are ignored due to truncation, so following 'below' text properties can still be made active. Similarly, a loop is needed to determine if a text property follows at the end of the screen.
