Specify a prerelease version in Project.toml compat section?

I have a clone of NativeSVG.jl at
GitHub - MarkNahabedian/NativeSVG.jl: A pure Julia SVG generator..
It’s Project.toml file designates it as

version = "0.1.0-naha"

which parses successfully as a VersionNumber.

VersionNumber("0.1.0-naha").prerelease
("naha",)

I have another package
GitHub - MarkNahabedian/ShaperOriginDesignLib: A library to aid in the writing of SVG files to drive the Shaper Origin CNC router. that depends
on it. Its Project.toml file has the compat entry

NativeSVG = "0.1.0-naha"

When I try to add ShaperOriginDesignLib to a workspace I get an error:

julia
Pkg.add(; url="https://github.com/MarkNahabedian/ShaperOriginDesignLib")
    Updating git-repo `https://github.com/MarkNahabedian/ShaperOriginDesignLib`
ERROR: Could not parse compatibility version for dependency `NativeSVG`

because the regular expressions at the end of
Julia-1.6.0/share/julia/stdlib/v1.6/Pkg/src/versions.jl don’t allow
for a :prerelease component in the version string.

Is this a bug?

How can I specify that ShaperOriginDesignLib depends on my branch of NativeSVG.jl?

Thanks.

It looks like there’s a similar issue with this constructor: VersionRange(s::AbstractString).
