Clicking the tag value on a tag page briefly shows a popup

Nobody has claimed this yet.

### What Happened?

On a tag page, clicking the tag value(same as the current tag page)in the **Tag** column of the default table view briefly opens a popup and then immediately closes it.

This may be happening because the action is attempting to navigate to the tag page, but the user is already on that page.

Regardless of the cause, the popup appearing briefly and then disappearing is distracting and negatively affects the user experience.

### Reproduce the Bug

1. Open a tag page.
2. In the default table view, find the **Tag** column.
3. Click the tag value corresponding to the current tag page.

### Expected Behavior

Since the user is already on the corresponding tag page, clicking the tag value should do nothing.

Start by reproducing the behavior on a tag page in the default table view, focusing on the Tag column value matching the current page. Trace the UI entry point for that value and verify that clicking it leaves the current page without opening a transient popup; confirm the behavior in the relevant table view.
