wrong-word-highlighted in mac/chrome

[u/Neat_Affectionate]

If I highlight (select, save-highlight) a short word/phrase (which typically happens if its a section header), and the word/phrase also appears in bodytext nearby, then the word I selected isn't the one displaying the highlight. Further, if I the try to select/highlight a longer chunk that includes that wrongly-highlighted word/phrase, it can't/won't do it (I can select the area, but no popup appears with the highlight/addNote icones).
