[ST] Discrepancies in swap and bridge estimates

[Tommy-R8]

Describe the bug Something must be broken regarding the estimate calculations on the Bridge or the Swap side (or both). See attached sceenshots, they were taken at the same moment in time, and the pool never moved in that time. The receiving side's (arbitrum) pool is really deep and balanced, so it should have almost no impact on the slippage.
