            Bug ID: 256047
           Summary: Auto-fit grid columns collapsing when container-type
                    set to inline-size
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Mac (Apple Silicon)
                OS: macOS 13
            Status: NEW
          Severity: Normal
          Priority: P2

Element with container-type: inline-size, display: grid, and auto-fit grid-template-columns collapses grid column widths to 0

Minimal error case:

https://codepen.io/darby3/pen/vYVZZEe

Summary: I have an element set to display: grid, with auto-fit columns. This works as expected.

As soon as I add container-type: inline-size, the grid width (column widths) collapse to 0 width. Switching to auto-fill columns, however, the columns work as expected.

While I didn't reproduce here, setting container-type to size appears to also collapse the height of the grid rows to 0.

I've noted mac apple silicon / macos above, but I've reports of this error on an iphone as well.
