See e.g. the official comment at <https://wpdev.uservoice.com/forums/257854-microsoft-edge-developer/suggestions/15885483-support-dataset-and-data-attributes-on-svg-element>.

I wonder whether it wouldn't be more pragmatic to add a note for the cases where `dataset` isn't supported on SVG elements rather where it is. I guess it would be a note about something which has nothing to do with the (HTML) specification but I believe it's more in line with what a web developer expects.

Agreed, will go with this for now and may change it later.

`dataset` is now de jure present on both HTML and SVG elements:
