Ggplotly geom_text with angle aesthetic

The “angle” aesthetic on ggplotly geom_text is implemented ?
Executing the following line:
ggplotly( ggplot(data=mtcars) + geom_text(aes(wt, mpg, label=rownames(mtcars)), angle=45) )
it returns no error but the labels are not rotated. However if I use a well know non-available feature like geom_label I receive the corresponding error “In geom2trace.default(dots[[1L]][[1L]], dots[[2L]][[1L]], dots[[3L]][[1L]]) : geom_GeomLabel() has yet to be implemented in plotly.”

Someone has already used this aesthetic in ggplotly ?

Thank you.
