dropdown mismatch #210
Description
When switching from the xtz/tzbtc dropdown item to the xtz/usdtz dropdown item, and then going to the liquidity tab, the pairing shouldn't reset to the xtz/tzbtc as it does now.
Moreover, after switching to xtz/USDtz in the dropdown in the liquidity tab, and then returning to the swap tab, the dropdown resets to xtz/usdtz, but the pairing displayed is still xtz-usdtz. the pairing shown for the swap (not the dropdown) however is not the correct one that's active though. That is, if a user nonetheless tries to trade XTZ-USDtz, a call is made for an XTZ-tzBTC swap instead.
