Regression: vcpkg does not add default features when a dependency is already installed

[dg0yt]

Port pango depends (by manifest) on the default features of harfbuzz, including harfbuzz[freetype].

$ vcpkg remove --recurse harfbuzz pango
The following packages are not installed:
    harfbuzz:x64-linux
    pango:x64-linux
$ vcpkg install --dry-run pango
Computing installation plan...
The following packages will be built and installed:
  * harfbuzz[core,freetype]:x64-linux -> 8.3.0#3
    pango:x64-linux -> 1.50.14#4
Additional packages (*) will be modified to complete this operation.
$ vcpkg install --dry-run pango harfbuzz[core]
Computing installation plan...
The following packages will be built and installed:
    harfbuzz[core,freetype]:x64-linux -> 8.3.0#3
    pango:x64-linux -> 1.50.14#4

Actual behavior

When harfbuzz[core] is already installed, harfbuzz[freetype] is not added to the installed set:

$ vcpkg remove --recurse harfbuzz pango
The following packages are not installed:
    harfbuzz:x64-linux
    pango:x64-linux
$ vcpkg install harfbuzz[core] >/dev/null 2>&1
$ vcpkg install --dry-run pango
Computing installation plan...
The following packages will be built and installed:
    pango:x64-linux -> 1.50.14#4
$ vcpkg install --dry-run pango harfbuzz[core]
Computing installation plan...
The following packages are already installed:
    harfbuzz:x64-linux -> 8.3.0#3
The following packages will be built and installed:
    pango:x64-linux -> 1.50.14#4

If not a dry run, this leads to a build error because pango needs hb_ft.h.

Similar, no change when only requesting harfbuzz without specifying [core]:

$ vcpkg remove --recurse harfbuzz pango
The following packages are not installed:
    harfbuzz:x64-linux
    pango:x64-linux
$ vcpkg install harfbuzz[core] >/dev/null 2>&1
$ vcpkg install --dry-run harfbuzz
Computing installation plan...
The following packages are already installed:
    harfbuzz:x64-linux -> 8.3.0#3

Expected behavior

After installing harfbuzz[core]:

• Installing pango should require a reinstallation of harfbuzz with freetype included.
• Installing harfbuzz should require a reinstallation of harfbuzz with freetype included.
