Description
### Is this a regression?
- [ ] Yes, this behavior used to work in the previous version
### The previous version in which this bug was not present was
_No response_
### Description
Example project: https://stackblitz.com/edit/angular-ivy-fojmnq?file=src/app/app.component.ts
A MatTable with sticky columns, MatSort and MatPaginator are created. After scrolling the table horizontally and clicking on sort header, some cells of sticky columns are rendered with offsets. After moving a cursor or tapping (on touch devices) the view is refreshed and looks as expected.
This issue appears only when not all of data present in MatTableSource.data is displayed. When page size of paginator is set that is show all the data, everything works fine.
### Reproduction
Steps to reproduce in example project:
1. Move horizontal scroll
2. Click on any sort header 2 times - try not to move cursor much
3. Sticky columns cells should display with offset or not display at all
4. After moving cursor, view is back to normal
### Expected Behavior
Sticky columns shouldn't change position after sorting data
### Actual Behavior
Sticky columns change position
### Environment
- Angular: 13.2.2
- CDK/Material: 13.2.2
- Browser(s): Chrome (v101.0.4951.64), Firefox(v100.0.2), Safari (v15.1)
- Operating System (e.g. Windows, macOS, Ubuntu): MacOS
Contributor guide
Research direction
Start with the linked StackBlitz example at src/app/app.component.ts and reproduce the issue by horizontally scrolling, sorting twice, and using a paginated data set. Compare the sticky-column rendering before and after sorting; done means sticky cells retain their positions without requiring cursor movement or a touch event.
