Bad interaction with crosstalk

[dmurdoch]

I'm not sure if this is a crosstalk issue or a manipulateWidget issue, but if I write e.g.

library(crosstalk)
library(manipulateWidget)
sd <- SharedData$new(mtcars)
combineWidgets(filter_slider("mpg", "Miles per gallon", sd, "mpg"))

the slider doesn't appear to get initialized properly, I just get a simple label and input box. (The real case has several widgets as well as the filter_slider, of course.)

This is using crosstalk 1.0.1 and manipulateWidget 0.8.0, both current on Github.

I'll post a link to this issue on the crosstalk repos.
