When the content is pasted (or set using the source edit mode), in IE a ""stack overflow"" error will occur. In Firefox, this can manifest as an ""unresponsive script"" error. It appears that the heavily nested nature of the document is what is causing the editor to hang or throw an error. When the content is viewed on its own in a browser or copied and pasted on a vanilla contenteditable div, the above mentioned performance issues are not noticeable. This seems to suggest that the performance issues are a result of the editor's processing on the document rather than a browser issue only.
