Short description of error
When pressing Space bar (in my case) to call the search, the text in the search field has the same color than the input field background making the text unreadable, the same happens in any of the search bar like in the Shading workspace when searching for a node over the Add menu.
Exact steps for others to reproduce the error
1- Call the Search (in my case is hitting Space Bar).
2- Write any words and you will noticed that the text is unreadable.
Thanks for your hard work :)
