👆 at the moment because the trailing slash check is for forward-slash-only, on Windows paths ending in a backslash hit that code path (which is removed in this PR). This means it will now fall through to the tryExtensions call on line 234, instead of the tryPackage call on line 243.

Note: Assumes a fixed #18299

There is a new eslint rule in place that prevents messages without dynamic content (or it is at least planned). I do see that it makes sense to have a individual message here, so we should either explicitly accept the message here or maybe just change the inner.js export content to contain a property with a string, remove the message and use deepStrictEqual. With the latter the error message should be explicit enough.

@BridgeAR If that rule ever comes to pass, we can always disable it with a comment for the instances where a string literal makes sense. So this can stay as is, if the proposed lint rule is the only motivation for changing it.
