SageMaker endpoint chat settings panel has region name that overlaps placeholder text

[JasonWeill]

Description

In the chat settings panel, when "SageMaker endpoint :: *" is selected as the language model, the default region name appears with "Region name (required)" superimposed on it.

Reproduce

1. Go to the Jupyter AI settings panel
2. Select "SageMaker endpoint :: *" as the language model
3. See the region name text box with both placeholder and text visible.

Expected behavior

As is the case when I click on the text box, the placeholder should appear at the top of the text box.

Context

• Operating System and version: macOS 13.5.1 "Ventura"
• Browser and version: Firefox 115.1.0esr
• JupyterLab version: 4.0.3, Jupyter AI tip-of-main

[dlqqq]

This doesn't appear to be an issue any more. I believe we fixed this in a separate PR but forgot to mention this issue.

I'll close this for now, and we can open a new issue if this problem persists. 👋
