Hi,
Both Context Menus of the parent grid and child grid appear when right-clicking on the child grid. This is an unexpected behaviour which can be replicated by running the attached code and:
1. Expand the first row
2. Click on the tab with title "Two"
3. Right-click on the first row of the child grid
I have attached images displaying the error.
I noticed that this behavior only happens in this particular scenario. Swap "One" with "Two" (i.e. the child grid is on the first tab, so you can perform steps 1 and 3 without step 2) and this behavior doesn't happen anymore; only the Context Menu of the child grid appears. However, upon clicking on the other tab and clicking back on this tab again, the buggy behavior will occur again.
