On lambdatest.com I could reproduce the issue with iOS 16.2, 16.4 seems to be working fine.

@susnux I think it might be related to a user picker or something like that. Might this be coming from one of our dependencies? I can't find the regex at that position of *.mjs file anywhere in our code: \\B(?<![^a-z0-9_\\-@.'\\s])

Edit: I think I found it: https://github.com/nextcloud-libraries/nextcloud-vue/blob/a2854e9cb99d0c14108180cbcee67f6240dfed70/src/mixins/richEditor/index.js#L32

May want to keep this open until my fix is released by the Vue library. It's targeted for 8.17.0.
