@neore is this the same as #8282 (which also stemmed from #4695)

After others tests :

• Chrome iOS v75.0 is affected too with "Aïe Aïe Aïe" error page or "Aw, Snap!" in English version.
• Firefox iOS v17.3 is affected too with force page reloading.

@neore on iOS, all browsers use the underlying Apple Webkit implementation.

Closing as duplicate #8282.
