Webapps don't support selecting by dragging

[Michael]

The webbrowser-app, and therefore webapps, don't allow you to click and drag to select text. Selecting text using keyboard (e.g. by pressing [ctrl]+[a] or by pressing and holding [shift] and then using arrow keys, works as expected.

Test case:
1. Open a webapp (e.g. Gmail)
2. Try select text by clicking and dragging

Expected result:
Selected text is highlited from the point where we clicked to the point that we dragged to.

Actual result:
No selection occurs.
