Describe the bug
During acceptance test, I noted that the Download window does not reset when clicking Download keyboard but retains the previous search. This is a little problematic after trying to use the Download window when offline (#302), because Keyman will not attempt to reload the page after failing here.

To Reproduce
Steps to reproduce the behavior:

1. Open Keyman Configuration and click Download
2. Do a search and select a keyboard, close the dialog.
3. Reopen the dialog -- it shows the last search result

Expected behavior
It should start a new search

Keyman for macOS:

• OS: macOS Catalina
• Keyman version: 14.0.190
