Don't use rectangular selection for highlighting

I can reproduce this. It shows a rectangular selection area instead of just highlighting text, and it's not possible to end the selection on a new line to the left of the start position.

I've looked into it and couldn't find a way how to make rectangle disappear during highlighting and most importantly how to make it allow to select the text to the left of the start of selection on the new line. I've asked PSPDFKIT team for suggestions.
