[Bug]: After sending a transaction on Polygon, send and swap transactions are being created with exceptionally high gas fees

[sleepytanya]

Describe the bug

After initiating a transaction on Polygon, send and swap transactions are being created with exceptionally high gas fees. I noticed the issue on Base and Optimism but further investigation needed.
This issue with elevated gas fees persists until a standard send transaction is executed. Following this, subsequent transactions are created with gas fees that fall within a typical range.

(This is build from the latest RC #29330)
