Just a suggestion: you can check the input size first and then apply semver "official" regex. There're no lookbehinds so it may be more suitable.
The key profit of lookbehind here is the redos-safe assertion that .a.b.c meta follows after -foo.bar.etc. Old good -(...*(\. ...* (+ ...*)?)?)?-based approach might significantly affect performance.

Page stays blank then, so it's pretty much unusable in any app that has to support all browsers.
