[Bug]: Summaries are not working properly with cell merge #16305
Description
Description
Scenario 1: Flat Grid with enabled summaries, cell merge, and group by. When grouping a column, the inner summaries are "collapsed"/treated like an igx-grid-row with merged cells. When clicking any of the summary row cells, the row is "expanded" and the summaries are visible. Clicking on other cells after that "collapses" the summary row again.
Scenario 2: Tree Grid with enabled summaries and cell merge. The layout is broken, i.e., not all cells and records are displayed, and errors are thrown in the DevTools Console.
- igniteui-angular version: 20.1.x, master
- browser: any
Steps to reproduce
- Use the attached sample that contains the abovementioned configuration.
- Observe the two grids.
Result
Flat Grid: The inner summaries are not displayed properly.
Tree Grid: The layout is broken, and no inner summaries are displayed.
Expected result
Inner summaries should be displayed the same way when cell merging is not enabled.
