Right-click context menu loses selection when timer fires

[carltonwhitehead]

Steps to reproduce:

1. Ensure at least two runs are on file, one with a time and one without a time
2. Right click on the run with a time to open a context menu
3. Trigger the timer to insert a time while the context menu is open before selecting an action
4. Select an action on context menu (ie DNF)

Expected result:
Action occurs on the right-clicked run

Actual result:
Action occurs on wrong run
