Session properties cleared on rotate; masking options exclusive

1.413.3

Patch Changes

• #4414 1b88c2f Thanks @marandaneto! - Clear properties registered for a session when the PostHog session rotates. (2026-08-06)

• #4374 b39b577 Thanks @dustinbyrne! - Persist in-place object and array mutations when properties are re-registered. (2026-08-06)

• #4434 75fb719 Thanks @arnohillen! - Make the session replay attribute masking options mutually exclusive: when both maskAllElementAttributes and maskAttributeFn are set, the coarse option wins and the callback is ignored (with a console warning), so a callback can no longer accidentally unmask what maskAllElementAttributes hides.
