Simon H	27eb91bbce	fix: dynamic namespace fixes and enhancements (#11219) ... * fix: fall back to component namespace when not statically determinable In #10006 we added more elaborate mechanisms to determine which namespace a given element is in. For `<svelte:element>` we added a "can't know at compile time" case and introduced a limited heuristic into the runtime. This doesn't work for a few reasons: - we're checking the parent's namespace to determine the current namespace, but the element itself could be the one that _changes_ the namespace - as mentioned in the previous comment already, on the first render we can't do any parent analysis - it does not take into account the static component namespace The last point is the crucial one: In Svelte 4, we're falling back to the component namespace if we can't know statically - e.g. if someone added `<svelte:options namespace="svg">` then `<svelte:element>` should fall back to that namespace instead. We were not doing that up until now, which introduced a regression. Fixing this also means getting rid of the (flawed) "can't know statically" heuristic. Fixes #10858, though for a complete solution we likely need some way to tell `<svelte:element>` the namespace at runtime through a special attribute. Maybe we can use `xmlns` for that like we do in the static case * support dynamic svelte:element namespace through xmlns attribute * fix	6 months ago
