qtconnectivity 'make install' installs src files to wrong location

During 'make install' two files are not exported under install prefix:

'/qt/qtconnectivity/src/nfc/doc/snippets/nfc_cppsnippet.js'

'/qt/qtconnectivity/src/bluetooth/doc/snippets/bluetooth_cppsnippet.js'

Those files should end up under install prefix as well?
This appears to happen for WebAssembly builds only.
