Fusion widget selection does not work well.

[libr]

steps to recreate:

1. Open any flexible web layout.
2. Click Buffer widget.

Note Buffer button is selected and highlighted.

3. Click other widget like Query.

Result: Both Buffer and Query seem selected, highlighted. To invoke buffer function again, you have to click it twice. This is fine in previous build and caused by the fix for ticket 497. All widgets have the same issue.
