install_man ignores install_tag from configure_file

[cepelinas9000]

Describe the bug
When trying to use install_tag with install_man(configure_file.. it is ignored.

To Reproduce
Minimal toy repository: https://github.com/cepelinas9000/meson-simpleprj

For example there are multiple install files with install_tag set:

• simplelib.so - xf86-plugin
• sample.4 - xf86-plugin
• sample.conf - xf86-plugin
• simpleprj - xf86-prj

If I performing meson install or ninja install, everything is as expected:

$ ninja install
[4/5] Installing files
Installing simplelib.so to /tmp/p1/lib64
Installing simpleprj to /tmp/p1/bin
Installing /home/as/proj/simpleprj/build/sample.4 to /tmp/p1/share/man/man4
Installing /home/as/proj/simpleprj/sample.conf to /tmp/p1/share/simpleprj

But if I use install with tags, the man file (sample.4) is ignored:

$ meson install --tags xf86-plugin
ninja: Entering directory `/home/as/proj/simpleprj/build'
[4/4] Linking target simpleprj
Installing simplelib.so to /tmp/p1/lib64
Installing /home/as/proj/simpleprj/sample.conf to /tmp/p1/share/simpleprj

Expected behavior
meson install --tags xf86-plugins or similar install tagged man files, for example:

$ meson install --tags xf86-plugin
ninja: Entering directory `/home/as/proj/simpleprj/build'
[4/4] Linking target simpleprj
Installing simplelib.so to /tmp/p1/lib64
Installing /home/as/proj/simpleprj/build/sample.4 to /tmp/p1/share/man/man4 << !!! expectation !!!
Installing /home/as/proj/simpleprj/sample.conf to /tmp/p1/share/simpleprj
