As far as I can tell this has been implemented, along with other
/review display options such as date range filters and sort order.
I've tested this by selecting the page size (and filter/sort options). This resulted in the following querystring:
Then, upon loading
/review on another machine, all settings were inherited from my other session, and on clicking other tabs the same querystring ispresent (as long as I avoided the suggested-edits tabs).
That was repeated using different combination of parameters. All behaved as expected.
As an aside,
pagesize can be set to any value between 15 and 1000. Values that are smaller/larger gets reset to the threshold values (15 or 1000). Invalid input resets it to 15.
