Passing in front of someone who has done 'Oseh Shalom' and has not returned to their place

Is it permitted to pass in front of someone who has stepped back for 'Oseh Shalom' and is waiting for the chazan to reach Kedusha?

There is room for caution, provided that due to this caution, one does not return to their place before the chazan reaches Kedusha.

Mishna Berura, Siman 123, S"K 6, and these are his words: "And the Magen Avraham wrote that according to what is brought by the Beit Yosef, there is an opinion that six steps are required, that is, three backward and three returning to their place (his intention according to the opinion of R' Manoach, brought in the Beit Yosef, who holds that the reason for the three steps is because it is learned from angels, and it is written, 'and their feet were a straight foot, and the sole of their feet like the sole of a calf's foot,' and here the foot is mentioned six times), therefore one must return to their place with three steps forward, and for this reason, some are careful that no one passes in front of them while they stand in the place where they stepped, so as not to interrupt their six steps, but nevertheless, due to their caution, they err, when they see someone wanting to pass in front of them, they hurry to return to their place before the shaliach tzibbur begins the prayer, which is the main law."
