In the horizontal row layout, size collapsed and summary row headers to the combined width of the columns they span instead of the first one, and do not measure auto-sized dimensions again from them. Closes #17222 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

🟡 Changes recommended
Resize limits still use the merged header width, allowing the divider to move beyond the resized dimension’s minimum boundary.

What changed in this PR
Backports #17847 to 22.2.x, addressing #17222 so collapsed and summary row headers fill their column spans in the Pivot Grid’s horizontal layout.
Changes:
- Uses the merged cell width for horizontal row headers.
- Skips previously auto-sized dimensions to prevent width inflation.
- Adds regression tests and a changelog entry.

Valid, fixed in 73a31cc: IgxPivotColumnResizingService.getColumnHeaderRenderedWidth() now returns the width of the resized (first) dimension when the header spans more columns, so the resize line stops where that dimension reaches its minimum width. Added a spec that drags a summary header resizer past the minimum. The same change is in #17847 and #17849.
Collapsed and summary row headers span several dimensions, but resizing changes only the first one, so measure that dimension for the resize line limits instead of the merged header. Closes #17222 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Closes #17222
Description
Backport of #17847 to 22.2.x.
In the horizontal row layout, collapsed row headers and summary (
Total) headers now fill all the columns they span. Before, they were only as wide as their first column.Motivation / Context
Regression from #16201 (20.1.0):
getHeaderWidthFromDimension()moved to the header group and returned its own column width (this.width) instead of the merged cell width (this.parent.width).autoSizeDimensionsInView()now skips dimensions that already have an auto width, so these wider headers do not widen them when it runs again. Resizing such a header changes only its first dimension, so the resize line limits are measured from that dimension.Type of Change (check all that apply):
Component(s) / Area(s) Affected:
Pivot Grid
How Has This Been Tested?
The specs from #17847 fail on 22.2.x without the fix, and the pivot grid specs pass with it.
Test Configuration:
Screenshots / Recordings
The issue shows the actual and the expected result.
