描述

Reproduction

https://angular-9-multiple-sidenav-scrollintoview-issue-1.stackblitz.io

Steps to reproduce:

  1. Close Sidenav 2 by clicking toggle button
  2. Run the following in browsers console: document.getElementsByClassName('mat-drawer-content')[0].scrollIntoView()

Expected Behavior

In this example nothing should happen.

Note: The scrollIntoView function works as intended. In this example nothing happens since content is too small to make page scrollable.

Actual Behavior

Entire page slides left. Notice how Sidenav 1 disappears. To better visualize the issue, you can at this point toggle sidenav 1. Button for sidenav 1 will no slide left out of view.

Environment

  • Angular: 9
  • CDK/Material: 9.0.1
  • Browser(s): IE 11
  • Operating System (e.g. Windows, macOS, Ubuntu): WIndows

Other Notes

This issue ONLY happens when Sidenav 2 is closed. There is no issue if Sidenav 1 is closed, or both sidenavs is closed or opened.

研究方向
Investigate the scrollIntoView behavior when multiple sidenavs are present, specifically when one is closed. Look at the sidenav component's scroll container logic in the Angular Material source code (e.g., src/material/sidenav). The issue mentions it only happens in IE 11, so consider cross browser compatibility. There is a StackBlitz reproduction that can be used to isolate the problem. Check if there are any existing tests for scrollIntoView in the sidenav.
