Page Width Consistency Issue with Obsidian SNW Plugin

[sfsdfc]

Hello,

I use the following CSS code to set the page width in Obsidian:

body {
  --user-custom-width: 703px !important;
  --file-line-width: var(--user-custom-width);
}

When SNW is not enabled, the page width remains consistent in both reading and preview modes. However, when I enable SNW, the page width becomes narrower in preview mode, as shown in the attached image.

Could you please advise on which parameters to adjust to maintain consistent page width when NSW is enabled? Thank you!
