Paging removes advanced filters

Device: PC
Browser: Firefox
OS: Win 10

Steps to reproduce:
- Go to Trade
- Go to Advanced Search
- Search using advanced filters and get more than 1 page of results (currently reproducible by searching for an

Archon Plate and selecting the "Ethereal" filter)
- Note: Page 1 of the results is filtered correctly, showing only ethereal Archon Plates (in this example)
- Navigate to Page 2
- Note: Page 2 looses the advanced filter and shows both, ethereal and non-ethereal

Archon Plate entries

Anything else to add:
A possibly related (or not) issue exists with the Trade Stats results paging/filtering. Going to my profile and then selecting "Active (All)" from the trade stats there, I've noticed that certain trades do not show on page 1. Then flipping to page 2 also does not show them (there is no page 3 yet mind you). Flipping back to page 1 after that then suddenly shows them. Haven't been able to figure out the exact cause/Pattern to this yet but the trades in question are not new so it isn't a refresh issue, I know that much.

I +1 on this one, any advanced search only works with page 1. Page 2 onward and it's a search with filters.
