When we zoom in or zoom out on in Safari, container queries are not affected by the change of the inline-size of the viewport. That particularly affect the user accessibility.

When you say "zoomed", how are you zooming? With Command-+, or pinch-zoom?
When zooming with Command-+. The normal behavior of the @container query on the `nav` element only appear when you increase or decrease the size of the viewport.
I think we fail to take 'zoom' property into account when evaluating container queries.
A new wrong behavior detected about container queries: * Set a `container` property in html element (as an Initial Containing Block) * Zoom+- in the webpage, nothing happen * Reload the page to see the zoom effect Don't know if this bug has to be fill in a new issue, but it sounds like to be involved in the same first reported (https://bugs.webkit.org/show_bug.cgi?id=249992#c0).
New wrong behaviors with a `container` property set on `html` element: * Once in a while, when you open a link in this page and clic on precedent the page is not rendering (a blank page occurs). * When media queries are updated from the device's operating system, or the user agent (`prefers-color-scheme` or `prefers-contrast` for instance) anything is updated, you have to reload the page to update the page and custom properties.
