Tasks: the task editor has the same state as the search bar when text is highlighted

The task editor and the homepage search bar appear to share state.

**Steps to reproduce:**
1. Navigate to the homepage and ensure that the search bar is cleared.
1. Navigate to the tasks page. Ensure there is at least 1 task (or create one first, with text in the editor).
1. Click on the gear-wheel of an existing task and select Edit.
1. When the editor loads, highlight some text in the editor.
1. Immediately navigate back to the homepage using the navigation bar.
1. Observe that the homepage's search bar has the text that was highlighted from the task editor from step 4.
1. Also, notice that the console will throw errors.
