Dirvish header and mode lines not displayed when using Emacs 30

Thank you for the bug report

• [X] I am using the latest version of dirvish related packages.
• [X] I checked CUSTOMIZING|EXTENSIONS.
• [ ] You may also try reproduce the issue using clean environment and minimal configurations with the command emacs -Q.

Bug description

I compiled Emacs from the main branch of the Git repository today. When using dirvish, the header and mode lines do not display anything. If I go back to Emacs 29.x, I see the mode and header lines normally, having the same package installed in both situations.

Here are the details from report-emacs-bug:

In GNU Emacs 30.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version
 3.24.38, cairo version 1.16.0) of 2024-03-07 built on asterix
Repository revision: 8aabd835747297818d538cc16b3f53fcc1dd67f6

I built Emacs from this commit hash 8aabd835747297818d538cc16b3f53fcc1dd67f6.

I can replicate this.

A lot of void-variable dv messages streaming through, might be related.
