UndefVarError: setexcludinghandlers! not defined

The following code

using Plots
plotlyjs() # without this line, this code generates a static graph.
plot(0:10, sin.((0:10)/3))

keeps emitting

UndefVarError: setexcludinghandlers! not defined
Stacktrace:
  [1] set_nosync(ob::Observables.Observable{Dict{Any, Any}}, val::Dict{String, Any})
. . . .

when run as include("try.jnl") from the julia REPL.

Julia 1.7.3 (2022-05-06) macOS 12.5

(up to date with juliaup).

Edit: Having kept searching the Net after my initial post, I finally found this discussion:

https://bytemeta.vip/repo/JuliaGizmos/WebIO.jl/issues/493

where a temporary workaround is shown: pin the package WebIO to version 0.8.17 . That has worked for me.
