Keep model when navigating back

[Redsandro]

When navigating back, I observe that all previously appended results are gone, and I end up scrolled back to the top where the first set of results are shown.

Is it possible to keep all the models, and when going "back", I go back to the page including all appended and autoloaded records?

Current behavior

• Visit infinity page, initially 50 items
• Scroll down
• Load a bunch of new pages; say 250
• Click item 250 - this changes route
• Go back to the previous page
• Only first 50 items are shown

Trying to achieve the following:

• Visit infinity page, initially 50 items
• Scroll down
• Load a bunch of new pages; say 250
• Click item 250 - this changes route
• Go back to the previous page
• 250 items are shown, scrolled down

Going "back" to an infinite scroll list after clicking on an item also causes OSX Safari to freeze for some seconds, and show number 200+ while secretly being reset to the first results. So if you click on (for example) number 240, it will open number 40 as if you clicked on 40. Safari Version 12.1 (14607.1.40.1.4)

@hhff commented:

the infinityModel method always assumes that you're starting from 0.

Perhaps a shouldFlushInfinityModel hook (or similar) could be the solution here! If you'd like to take a stab at that, we'd very much appreciate it.

So Safari has this back/forward cache that when going back always assumes you're starting from exactly the state where you left off. How do other people deal with this?

This seems to be the opposite problem.
