is one piece episode 917 filler?

Newspapers reach Kuraigana Island, the island where Zoro trained. Dracule Mihawk receives a newspaper from one of the birds.

Perona also sees the newspaper and is shocked to see Moria's image on the front page, apparently having carried out a zombie raid. She is happy to hear that Moria is still alive and decides to leave to see him again.

Before she leaves, Mihawk tells her that leaving was the best decision, as a strange topic was brought up at the Levely. Meanwhile, on Fullalead, a island dubbed the "pirate paradise," Blackbeard sits in the shadows near a newspaper depicting Sabo.
