Routes with overlapping prefixes shadow more specific routes depending on registration order V3.6.0

[drmaus83]

Description:

When two routes share the same HTTP method and one path is a prefix of the other, the shorter route intercepts requests intended for the longer one if it's registered first.

Example:

// Registered first
server.on("/api/resource", HTTP_POST, handlerA);

// Registered second
server.on("/api/resource/action", HTTP_POST, handlerB);
A POST to /api/resource/action hits handlerA instead of handlerB.

Reversing the registration order (specific route first) works around the issue.

Workaround: Register the more specific route before the general one, or use non-overlapping paths.

I only tested this with POST method but i imagine it might happen with others

Is this expected or would this be considered a bug? If it is considered a bug has it been addressed in newer versions?
Version 3.6.0 is just the most current version in the platformio registry

This is not a bug but an expected situation which is documented and also on the examples.

ok thank you i did notice something was mentioned in the docs about how it matches strings good to know, just didn't want to report a bug if it was intentional.
