when selecting text, the App navigation bar opens #282

Hey,
here are the steps to reproduce:

• open a note in browser, resize the window so that the sidebar automatically hides
• mark two lines of text with the mouse, starting in the beginning of a line and dragging bottom-right to the end of the line
• the sidebar opens and the text you wanted to select is not completely selected

workaround: start selecting text at the bottom right corner and drag upwards and to the left.

this is a little annoying because I do this quite a lot and everytime it doesn't work. With every other text/app I use, I can select text from top left to bottom right no problem.
