Force full serifs for turned m under monospace. (#2127)

changes/28.0.2.md

@@ -6,4 +6,3 @@
 * Make serif variants of Cyrillic Small Letter Tall Te (`U+1C84`) respond to italics.
 * Make terminal serif behavior of palatalized Komi consonants (`U+0502`...`U+0505`, `U+0508`...`U+050F`) more consistent with each other.
 * Refine serifs of Turned M (`U+019C`, `U+026F`, `U+0270`, `U+1D1F`, `U+1D5A`, `U+1DAD`), Cyrillic Sha (`U+0448`, `U+2DF2`, `U+1E046`, `U+1E064`), and Cyrillic Shcha (`U+0449`, `U+2DF3`) under monospace.
-  - As a consequence, serifed and motion-serifed variants will look identical under monospace.
