Template selection considers last media type suffix (alphabetically) instead of first (by slice order) #13877
Description
This is not a recent regression; the behavior exists in v0.146.0 and later.
While updating the docs for the new template selection logic, I ran across this:
Note that if the output format’s Media Type has more than one suffix defined, only the first is considered.
I wanted to verify that the behavior had not changed, and found that with v0.146.0 and later, only the last (sorted alphabetically) is considered.
site config
[mediaTypes.'text/html']
suffixes = ['b','a','d','c']
[outputFormats.html]
mediaType = 'text/html'project structure
./
├── content/
│ └── p1.md
├── layouts/
│ └── _default/
│ ├── page.html.a
│ ├── page.html.b
│ ├── page.html.c
│ └── page.html.d
└── hugo.toml
With the example above, layouts/_default/page.html.d is used instead of layouts/_default/page.html.b. However, the page is published to the correct path:
public/
└── p1/
└── index.b <-- extension is correct, but wrong template is used
This example is obviously contrived, and I suspect a rare configuration/setup.
Test case to follow.
