Legacy reactlog is broken

[jcheng5]

options(shiny.reactlog=T)
shiny::runExample("01_hello", display.mode = "normal")

I can't repro now 😕

[jcheng5]

It doesn't repro unless you launch a second tab. I was seeing this in RStudio when pairing with @schloerke because the Shiny app was launching in the Viewer, then I'd hit the "Open in new window", then Cmd+F3 on that new window.

Git bisect points to 7168251. I had to do a bunch of git skips because some of the commits either would halt the session immediately or depended on packages that no longer exist (promise (without an "s"), system2.5).

Could this explain #1694? That was an issue already before 7168251 though.
