Text selection (thus Highlight) is impossible if another previous highlight exists and overflows from previous line to the beginning of the current line
Using Evince 3.36.7
Has can be seen in the picture, I have a highlighted piece of text than spans on 2 lines on the text "industry-scale⮰recommendation".
When I move the cursor on the line with the second part of the highlighted piece of text, it takes the shape of the "Annotation Editing" cursor (hand shape can be seen in picture), making it impossible to select some text on this line, thus to highlight another piece of text on the next line.
