[FIX] web: ignore incorrect Safari errors

Steps to reproduce: (on Safari only)
1. Install Email Marketing and Mass mailing on sale orders
2. Open Email Marketing and try to open 'Our last promotions, just for
   you!'
3. An error is thrown

Solution:
Ignore errors raised in Safari

Problem:
Error "ResizeObserver loop completed with undelivered notifications." is
raised by the ResizeObserver in
`mailing_mailing_view_form_full_width.js`. However in Safari (and
desipte the ResizeObserver flow being exactly the same than in other
browsers), the error message is "Script error." so we are not able to
correctly discard it in the error listener of `error_service.js`
