- [x] our [DataClone error](d733abfca0/components/script/dom/bindings/error.rs (L80)) needs to support an optional message - [x] we need to add support to our DOMException implementation to allow an optional message to replace the default message - [x] we need to create a new struct used by both StructuredDataReader and StructuredDataWriter for storing the error message in the report_error_callback - [x] report_error_callback needs to cast the closure pointer to the new struct - [x] the code that [throws a DataClone error](5d1c64dba9/components/script/dom/bindings/structuredclone.rs (L542)) needs to use the stored error message if it's available Testing: *Describe how this pull request is tested or why it doesn't require tests* Fixes: #36191 --------- Signed-off-by: jerensl <54782057+jerensl@users.noreply.github.com>
