The Listing window's "Show Tab List" button can become completely hidden even when the window is large enough to display it

Describe the bug

In CodeBrowser's Listing window, the "Show Tab List" button can become hidden if the window is made just small enough to cut it off completely (see screenshots).

I stumbled upon this issue accidentally when I opened a project with four code listings. Despite only three tabs being visible in the Listing window, the "Show Tab List" button was not displayed. I had just upgraded Ghidra, so it took me several minutes to realize that the button was simply obscured and hadn't been moved or removed by the new version of Ghidra.

To Reproduce

Steps to reproduce the behavior:

1. Have enough tabs in the Listing view to make the "Show Tab List" button appear.
2. Grab the right edge of the window and drag it left until the "Show Tab List" button is no longer visible.

Expected behavior

The rightmost visible tab should be hidden if the "Show Tab List" button is at all obscured.
