P3An issue that is relevant to core functions, but does not impede progress. Important, but not urgentAn issue that is relevant to core functions, but does not impede progress. Important, but not urgentarea: material/tabs
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
probably never worked
Description
The scroll position of a mat-tab-nav-bar is not clamped to the max scroll distance when tabs are removed, but is still scrollable.
Reproduction
Steps to reproduce:
- Open Stackblitz: https://stackblitz.com/edit/components-issue-s5jn1k?file=src/app/example-component.ts
- Scroll all the way to the end of the tab nav
- Click on the button to remove the first 2 tabs
- Tabs scroll out of view, because scroll position is not reset to _getMaxScrollDistance
Related: Clicking on the button again to remove another 2 tabs scrolls the content back into view, because now the nav bar is no longer scrollable (this was fixed by #23759)
Expected Behavior
Scroll position is never greater than maximum scroll distance
Actual Behavior
Scroll position remains the same, tabs are scrolled out of view
Environment
- Angular: 13.1.1
- CDK/Material: 13.1.1
- Browser(s): Chrome
- Operating System (e.g. Windows, macOS, Ubuntu): Windows 10
