In both 1.11rc and nightly:

julia> using InlineStrings

julia> a = Base.AnnotatedString("annotated", [(1:9, :label => 1)])

julia> b = InlineString("abc")

# correct:
julia> a * b
"annotatedabc"

# wrong:
julia> join([a,b])
"annotated\x03cba"

# correct:
julia> join([String(a), b])
"annotatedabc"

julia> using InlineStrings

julia> str = Base.AnnotatedString(InlineString("abc"))
"abc"

julia> sprint(print, str)
"\x03cba"

The problem is that AnnotatedStrings thinks that print and write are the same thing:

Treat printing as more than a noting-return write
2c745e6 
As raised in <JuliaLang/julia#55198>, once
we look at AbstractString types outside of Core/Base, their print
methods can be meaningfully different to write + returning nothing.

As such, instead of delegating printing to write, we need to call
_ansi_writer asking it to use the print function.

This is fixed in JuliaLang/StyledStrings.jl#66, I'll let tests run then merge + bump + backport.
