Describe the bug

In the Groups view (default/flat view), when using the name filter and no groups match the search criteria, removing the filter text causes the filter/search bar to disappear completely. Additionally, no groups are displayed afterwards, even though they should reappear when the filter is cleared.

Version

26.1.5,26.2.1

Regression

[ ] The issue is a regression

Expected behavior

When clearing a filter in the Groups view that returned no results:
1. The filter/search bar should remain visible
2. All groups should be displayed again after the filter is cleared

Actual behavior

When clearing a filter in the Groups view that returned no results:
1. The filter/search bar disappears completely
2. No groups are shown at all, even though groups exist
3. The view becomes unusable for further filtering

How to Reproduce?

1. Log into the Keycloak Admin Console
2. Navigate to the Groups section
3. Ensure you are in the default (flat) view, not the hierarchical view
4. Enter a search term in the filter that matches no existing groups (e.g., "xyz123")
5. Observe that no groups are shown (expected)
6. Clear the filter text
7. Observe that:

• The filter/search bar disappears
• No groups are displayed
• There's no way to get back to the normal group view without refreshing the page

Anything else?

• The only way to recover from this state is to refresh the entire page, which impacts the user experience and workflow efficiency
• Important: This issue does not occur in the hierarchical view of the Groups section, only in the default (flat) view
• The hierarchical view's search functionality works as expected
• Issue has been verified in both Keycloak 26.1.5 and 26.2.1
