Selection doesn't work as expected at the end of a Paragraph. If the user holds down the mouse button down and drags just after the paragraph end (in the free space after the last line), the end of paragraph symbol is unexpectedly selected when the mouse hovers the end of paragraph symbol.

Instead, the first letter before the paragraph end should be selected, but only after the mouse hovers it.

Steps to reproduce: 
- Add two paragraphs.
- Click in the empty space just after the end of the last line of the first paragraph, and start moving in direction of opposite to the text flow (left in LTR text case).
Expected: Text is selected only after the mouse passes the first symbol before the paragraph end.
Actual: Paragraph end symbol is selected as soon as the mouse hovers it.
