Text selection in note changes note formating

[mkyral]

When selecting a text in the note and there is a mix of formatting (e.g.: part is bold or in different colour), the formatting is changed.

Steps to reproduce:

1. Create new note, put several words inside
2. Select part of text and change style to bold
3. Start text selection somewhere in normal weight text and continue selection over the bold formatted text - the formatting of all selected text will be changed (unified)
