script_bindings: Check for null pointer before dereferencing proxy handler custom data (#36869)HEADmain
While the vast majority of DOM proxy objects created have a non-null
pointer in the handler's extra data field, there is one place we create
a proxy object that has a null pointer:
https://github.com/servo/servo/blob/8b05b7449d3ceaeb6ae834246012ac04a4f048c6/components/script/window_named_properties.rs#L76
. Before #36818, dereferencing this null pointer was undefined behaviour
that was silently being ignored; now that Rust 1.86 adds debug pointer
validity checks, we get a panic when trying to dereference it.
Testing: Tested about:memory with rustc 1.86.
