Reproducible on Firefox Preview Beta 5.2.0-beta.1 GV:78 with Google Pixel 3 XL (Android 9) and Samsung Galaxy S9 (Android 8). And a small remark is that when selecting 2 rows from https://dataride.uci.ch/Results/iframe/EventResults/220062?competitionId=59800&disciplineId=7 , the last selected cell from the last column is not highlighted, even though when it is pasted it's displayed ok.
