PDF viewer sidebar does not close when clicking the hamburger menu icon at the top left

How to Reproduce?

1. Go to any PDF and open it using Helium (i.e., https://ontheline.trincoll.edu/images/bookdown/sample-local-pdf.pdf)
2. Click on the hamburger menu icon at the top left.
3. Sidebar does not close.

Actual behavior

When opening a PDF through Helium, the sidebar on the left does not close.

The sidebar should close and open up when you click on the hamburger menu icon.

Odd... it's working for me on macOS using build 0.8.4.1. Have you tried it in an Incognito Window?

@kwehner Just did, same issue.

I have the same bug on Arch Linux,
Version 0.8.4.1 (Official Build, Chromium 144.0.7559.109) Arch Linux (64-bit)

[input-Here]

I can confirm I am also having the same issue. Also, the pdf never appears to be centred, even before toggling the sidebar. Running 0.8.4.1 on Windows 11 24H2 (64-bit).

yep, that's my bad. i made the sidebar's width dynamic in #815 (to make use of as much space as possible), but that breaks its collapsed state sometimes.
