REGRESSION: Using linear advance on prusa i3 MK2 and wipe on retract causes blobbing

As the title says, with 4.1.0 there is blobbing introduced if linear advance is enabled with retract on wipe enabled

Disable wipe on retract, the issues go away.

Disable linear advance, the issues go away.

Going back to version 4.0.1 also solves the issue meaning that this is a bug introduced in 4.1.0


I'm using the prusa i3 MK2 with stock firmare. Linear advance has been enabled using the gcode command M900 K30 as recommended by prusa.
