Extrusion rate smoothing does not work when moving to another island

Is your feature request related to a problem?
Extrusion rate smoothing is ON:
max_volumetric_extrusion_rate_slope = 5mm^3/s^2
max_volumetric_extrusion_rate_slope_segment_length = 3
This works well as long as you don't go off-island.
In the case when we have several islands (several parts), when moving the extruder to another island, the speed іьщщерштп does not work at all. As a result, the new permeter starts printing at a different speed, which has changed dramatically. This leads to overextrusion at the beginning of the perimeter.
Which printers will be beneficial to this feature?
Marlin
Describe the solution you'd like
Before moving to another island, the extruder must gradually change its speed to match the speed of the extruder on the new island.

The same problem exists when moving to a new layer. I think this feature is not fully done yet.

Please re-open this bug report. I am currently struggling against sudden extrusion changes between loops (islands) in the same layer, when using TPU. When jumping from a low loop on a small island to a large loop of a large island (in the same layer), I get underextrusion. The other way around I get overextrusion. TPU is specially susceptible to this issue and demands inconvenient workarounds and reprints. I consider this a clear bug.
