Parent double-dot path step in application manifest asmv1:assembly/file/@name throwing error

In building from NuGet, the application manifest includes a number of asmv1:assembly/file/@name values that have a double dot, e.g.,
<file name="lib\fedora-x64\native\..\libgit2-106a5f2.so" size="1198160">

This throws an error, e.g. (via SxsTrace):
ERROR: Line 449: The value lib\alpine.3.9-x64\native\..\libgit2-106a5f2.so of attribute name in element urn:schemas-microsoft-com:asm.v1^file is invalid.

It seems that the root of this issue is https://github.com/libgit2/libgit2sharp.nativebinaries/blob/9469eab266bacdbb46aed4610b3b0e6bbfc56395/nuget.package/build/net46/LibGit2Sharp.NativeBinaries.props#L11

There the double-dot parent path is hard coded to be imprinted and negate native.

I propose the removal of ..\ in attribute TargetPath or something similar. Keeping the native subdirectory shouldn't harm anything. At any rate, ISTM the syntactical constraints of asmv1:assembly/file/@name should be respected.

Start with the LibGit2Sharp.NativeBinaries.props entry linked in the issue, especially line 11 and its TargetPath value. Rebuild from NuGet and verify that the generated application manifest no longer contains the parent path step and is accepted by SxsTrace.
