M486 Cancel object causes pause

I have a print going right now for which I had to cancel an object (object 0 of 0-4) because it lost bed adhesion. M486 cancelled the printing of the object as expected, however, now the printer pauses at the final position for object 4 for about 3sec before proceeding to object 1.
I assume this pause is happening while skipping past the gcode for object 0, but is this pause expected behavior? It's not really a problem for this particular print since infill is the last feature to print per layer, but if I were printing no infill and external perimeters last it would certainly result in visible blobs.
Anyway, just wanted to find out if this is expected and, if so, are there any strategies to reduce the length of the pause while the canceled object's gcode section is skipped.
I'm running RRF 3.3 on a Duet 2 Wifi in a Rostock Max
@ajdtreyd the firmware needs to reed the gcode file until it finds the next object. depending on the number of gcode lines in the object being skipped this could take some time - leading to a perceptible pause.
There is not a strategy to reduce this pause right now (although as you point out printing in fil last will help mitigate the impact). We are discussing options for improving this in the future.

Hello there, I'm contemplating whether PrusaSlicer could get support for the recently added M486 order that Marlin presented in v2.0. I realize this component is executed along these lines in with the drop objects octoprint module however it seems like that module hasn't been refreshed in some time. What's more, with the coming help of Python 3, that module may fall into a state where it can presently don't be utilized. Here's some more data about how marlin carries out it.
RRF doesn't care whether objects are labelled using M486 or using comment lines, because it recognises both. PrusaSlicer already has a "Label objects" option on the Print Settings page, and that generates comments that are sufficient for RRF to implement object cancellation.
