[Bug][MOBILE] Problems with selection of text in received letters

[tprudentova]

0.12.1 tested on Android; mail.stg.lin-saas.com

1. Receive a letter, open it
2. Try to select text to copy it
3. It's really hard to do it (I think you need to long-tap it for too long, and the block for selection is too narrow, so it's not very intuitive)
4. Once you select text, it's impossible to unselect

Expectation: I can select text by long-tapping it for like 0.3 sec (not sure about exact time, please check the way it's done in other email clients). I can unselect by clicking on any other part of the screen
