Commit [1] added a regular expression that looks behind to ensure a `-` is present without capturing it. Unfortunately, the Positive Look Behind regex (?<=...) is unsupported by Safari as of now (16.1, see [2]). This commit replaces the regex by removing the '-' after capturing it. Steps to reproduce: - Use Safari - Install website_event - Try to edit any page with website - "Invalid group specifier name" error appears [1]: https://github.com/odoo/odoo/commit/5f1f082dbe268522f8fc7e63ad5f564b25020a22 [2]: https://caniuse.com/js-regexp-lookbehind opw-3049537 opw-3023128 opw-3023329 closes odoo/odoo#105076 X-original-commit: 08413daa7b62539f86110575f1835d6db271ea10 Signed-off-by: Romain Derie (rde) <rde@odoo.com>
