Clicking two different tool buttons quickly opens the configuration dialog
#### Summary:
When a tool button is double-clicked, Inkscape brings up the configuration settings dialog for that tool. This is good.
However, when two _different_ tool buttons are clicked within the double-click threshold, it is incorrectly counted as a double-click and the configuration settings dialog opens.
#### Steps to reproduce:
- Open Inkscape.
- Click two tool buttons within a brief period of time.
#### What happened?
- A configuration settings dialog opens.
#### What should have happened?
- The second tool should be active, with no dialog opened.
#### Debug info
I see this behavior with the Inkscape 1.2 development builds, but not with Inkscape 1.1 production.
