Why 1.0.0-alpha-9.9A < 1.0.0-alpha-9.10A is true

[xflcx1991]

compare-versions，6.1.1
According to https://semver.org/, dot-separated identifiers with letters or hyphens are sorted by ASCII values
Then 1.0.0-alpha-9.9A and 1.0.0-alpha-9.10A should be sorted by ASCII with "9A" and "10A", the first character '9' > '1',so it should be "1.0.0-alpha-9.9A" greater than "1.0.0-alpha-9.10A", but the result is the opposite.

But if changed to "1.0.0-alpha-9. A9A" and "1.0.0-alpha-9. A10A", "1.0.0-alpha-9. A9A" is bigger.

It seems that if a dot-separated identifier is prefixed with a number, compare-versions will be compared numerically, which does not meet the rule of "Identifiers with letters or hyphens are compared lexically in ASCII sort order".

I used npm install --save semver and it strictly followed the rules, please see

console.log(compareVersions('1.0.0-alpha-9.9A', '1.0.0-alpha-9.10A'))
console.log(semver.gt('1.0.0-alpha-9.9A', '1.0.0-alpha-9.10A'))
console.log('-------------------------------')
console.log(compareVersions('1.0.0-alpha-9.A9A', '1.0.0-alpha-9.A10A'))
console.log(semver.gt('1.0.0-alpha-9.A9A', '1.0.0-alpha-9.A10A'))

output

-1
true
----------------------------------
1
true

So is it a problem?

Another example of different results from the semver library:

console.log(compareVersions('10.2.2-rc.19', '10.2.2-rc.1a')) // 10.2.2-rc.19 > 10.2.2-rc.1a
console.log(semver.lt('10.2.2-rc.19', '10.2.2-rc.1a'))  // but semver says 10.2.2-rc.19 < 10.2.2-rc.1a
