This is a long standing request from developers. It's particularly useful on Mobile, where context lost is more common. We have discuss the potential to support in canvas and received approval from webkit (https://github.com/whatwg/html/issues/4809#issuecomment-641546468) and firefox (https://github.com/whatwg/html/issues/4809#issuecomment-640961008)
(note that kenrussell's comment at https://github.com/whatwg/html/issues/4809#issuecomment-698018630 explains why we need both context lost and context restored events ).

I am filling this implementation bug for firefox to support it in the future.
