Steps to reproduce:

1. Create a Tag "test".
2. Create a Tag "child" below the "test" Tag.
3. Go to the "Root" tag and ensure that the "test" tag is collapsed, so that the "child" tag is not visible.
4. Search for "child" in the search input above the Tags tree. The "test" tag is expanded to show "child".
5. Abort the search by clicking on the "x" icon.
6. The "test" tag is collapsed again but the expand icon stays in the expanded state.

Result:
The expand icon is in the expanded state.

Expected result:
The expand icon should be in the collapsed state.
