Parsing f."a" causes a "malformed-expression" error with include

[tshort]

The syntax f."a" parses fine at the REPL, but it fails when the code is loaded with include:

julia> open(io->println(io, """f."a" """), "bug.jl", "w")

julia> include("bug.jl")
ERROR: LoadError: syntax: malformed expression
Stacktrace:
 [1] include at ./boot.jl:314 [inlined]
 [2] include_relative(::Module, ::String) at ./loading.jl:1067
 [3] include(::Module, ::String) at ./sysimg.jl:29
 [4] include(::String) at ./sysimg.jl:68
 [5] top-level scope
in expression starting at /home/tshort/FS/appfiles/julia/MDPad/bug.jl:1

julia> f."a"
ERROR: UndefVarError: f not defined

Hyperscript uses this syntax. See the the bug report here: JuliaWeb/Hyperscript.jl#7.

Note that the error doesn't occur with f.`a` .

Dup of #26739?

[tshort]

It may be the same root cause as #26739, but the symptoms look different to me. The syntax works at the REPL but not with include.

julia> f() = 1
f (generic function with 1 method)

julia> Base.getproperty(::typeof(f), ::String) = "Hello"

julia> f."a"
"Hello"

julia> open(io->println(io, """f."a" """), "bug.jl", "w")

julia> include("bug.jl")
