However, the same logic should apply to older iOS as well. So will update in a separate PR. Basically we were using `firstRectForRange` incorrectly. According to [the API doc](https://developer.apple.com/documentation/uikit/uitextinput/1614570-firstrectforrange), `firstRectForRange` should return **the rect for the queried range, or a subrange through the end of line, if the range encompasses multiple lines**. For LTR language: ``` 0, 1, 2, 3 4, 5, 6, 7 ``` Query: `[1, 2, 3, 4]` Returns the following rect denoted by `[ ]`: ``` 0, [1, 2, 3] 4, 5, 6, 7 ``` Similarly, for RTL language (Arabic): ``` 3, 2, 1, 0 7, 6, 5, 4 ``` Query: `[1, 2, 3, 4]` Returns the following rect denoted by `[ ]`: ``` [3, 2, 1], 0 7, 6, 5, 4 ``` *List which issues are fixed by this PR.
