fastmap < 1.1.0 did not have a faststack function, which htmltools depends on. This creates an installation error in some environments (particularly upgrades):
object ‘faststack’ is not exported by 'namespace:fastmap'
As a result, we should pin fastmap (>= 1.1.0) in the DESCRIPTION file or relax the need for faststack

shiny
pins to >= htmltools 0.5.2, so this issue will probably hit in other places as wellhttps://github.com/rstudio/shiny/blob/54e5a6b43c4d2d4e24e571e71a9773be046531b7/DESCRIPTION#L82
