These functions do work correctly when the iframe's src was not changed, or if they are not in an iframe at all. Calling pushState after the iframe loads but before the pushState in the iframe is called seems to fix the issue. To reproduce the issue, unzip the attached zip which contains index.html and embed.html. Open index.html. It will load embed.html into an iframe. Open the console and click 'push history' under 'frame 2 (src change)'. See that history.length does not change. Then click 'push history' under 'frame 1 (no src change)'. See that history.length does change. Replicated on Safari 14.1.1, latest WebKit (r279353), and iOS Safari on iOS 14.6. Firefox and Chrome do not have this issue. 1774888 1 webkit-bug-importer 2021-07-05 19:45:17 -0700 <rdar://problem/80190653> 432448 2021-06-28 19:44:46 -0700 2021-06-28 19:44:46 -0700 minimal working example test_case.zip application/zip 867 richy.liu.2002 UEsDBBQAAAAIAEWZ3FJsVIzvTQEAAMsCAAAKABwAaW5kZXguaHRtbFVUCQADAoHaYEGB2mB1eAsA AQT1AQAABBQAAACNUkFPgzAYvfsrPuuhkBkIuw4wUZfoSRO9eFqgfEC1tAt8LJJl/126jmUzxuxA +uC9773X0vj68eXh/eN1CTU1Kr2K3QIQ15gVFoyQJClM876KQwctH06CODfFcFAWcuOQNYjSss0a hAg8baBrBYg60xX642x0lEknkkXC9ihiVpowbHIsAluHpXHoVIeU8Bjzd+AcvEvT5pemOdyJVq5p ciuM6BvUFFRIS4UW3g/PhcedNfcDW2OWAL/Zd5G6WlGNq75VfHEwnxzda94TGQ1GCyXFV8LWfVc/ yY5MO3g+S8dzJJAaXD8fLA214+PQDaenTYGGNSaM8JvCz2yTua9s2kDZa0FyDDzLge2BBhBGd0Zh oEzl8RxL0yJwmE2ZgUJdUe0vjgMTYQ3fKCP0trtb4Hx87kpj+In0zDsrCdv/rHe/zstid/HG/7u/ sz9QSwMEFAAAAAgAtZncUpjtS27YAAAAfQEAAAoAHABlbWJlZC5odG1sVVQJAAPWgdpg/4DaYHV4 CwABBPUBAAAEFAAAAH2Qz07DMAzG7zyF6SWdQMsDkJUDIHFj0rhwTFN3CWRx1brTqmnvTotbxC4c ovjPz5/lz9w+vz29f2xfwPMhFjdGPgDj0VZTMIYcOGKBhxIroyWZCL0gpqRqmNmyZ6YElFwM7muT NX3nX0PH1A75KiumFLzkRgs8T3auDQ0DDw1uMsYT6097tFLNhAGo++Q4jAuudOE8twEcpY4iriPt c1ViTS2Cgrtl5zpi2rNfPfwOLI1JcMeWMT9f7kGp8T3WROoPeqVta8b2P+mLnKXlAnFMjBqd+3H5 G1BLAQIeAxQAAAAIAEWZ3FJsVIzvTQEAAMsCAAAKABgAAAAAAAEAAACkgQAAAABpbmRleC5odG1s VVQFAAMCgdpgdXgLAAEE9QEAAAQUAAAAUEsBAh4DFAAAAAgAtZncUpjtS27YAAAAfQEAAAoAGAAA AAAAAQAAAKSBkQEAAGVtYmVkLmh0bWxVVAUAA9aB2mB1eAsAAQT1AQAABBQAAABQSwUGAAAAAAIA AgCgAAAArQIAAAAA
