iOS 26 beta3 Custom keyboard always displays a gray bar above it

Problem description: When using the Custom keyboard in various system application scenarios, a gray area is always displayed at the top of the Custom keyboard. Although the system has been restarted and the Custom keyboard has been restarted, and the pull-down operation has been repeated in multiple system application environments, the gray bar still appears. This problem also has the same problem on other input method software.

Reproduction steps:

  1. Set the current input method to "CustomKeybaord"

  2. In the memo app or any other system app, pull up the Custom keyboard, or switch to the Custom keyboard.

  3. Observe whether a gray area is always displayed above the Custom keyboard.

Request: I would like to understand whether the current behavior is a bug or if it requires Custom keyboards to adapt their style accordingly. However, I not found that currently unable to modify the style or color of the gray bar in question, and I do not have a suitable adaptation solution at this time. I would appreciate further assistance
