Search box, issues when empty

• When the search box is empty, pressing the search button should not display that tiny floating rectangle. See gif.

Style suggestion: Maybe center the box and the button in the header row, instead of the button going off grid.

In Version 114.0.5735.111 (Official Build) (64-bit) the search function does not work: the tiny rectangle is shown regardless of the content of the search box, and no search is performed.
