Open in Safari on iPhone, zoom the app very fast, see the page is crashed.

Might be fixed here https://github.com/bryntum/bryntum-suite/pull/9126 Tested in the branch - not reproducible. Required confirmation of the reporter after next patch release.

Client has replied back and reported that it is not fixed for him in the 6.0-alpha-3 as well so we need to re-check this.

Ckient has reported that this happens when a "Bootstrap" modal is shown. Can we test that? Bootstrap?
