[Bug] Hermes Desktop: PageUp while input is focused breaks page layout (sidebar gets squeezed out, content shifts left, blank space at bottom)

[Murphy-Tong]

Bug Description

In Hermes Desktop, pressing PageUp while the chat input box is focused causes the page layout to break:

• A large empty area appears at the bottom of the chat view.
• The chat content shifts to the left.
• The left-hand menu/sidebar area gets squeezed out / disappears.

PageDown likely has the same problem (worth confirming).

Steps to Reproduce

1. Open Hermes Desktop.
2. Click into the chat input box (focus it).
3. Press PageUp.
4. Observe the layout breaking — large blank area at the bottom, content shifted left, sidebar pushed off-screen.

Expected Behavior

PageUp inside a focused input field should either:

• Do nothing (default browser/Electron behavior should not affect layout), or
• Scroll the chat transcript up by a page without touching layout dimensions.

It should not distort the page layout or hide the sidebar.

Actual Behavior

Layout breaks as described above. A page refresh / window resize is needed to recover.

Environment

• App: Hermes Desktop
• OS: Windows 10

I am running into this exact same issue. The visual symptoms match, so I assume it's the same underlying bug, even though reproduction steps are different.

Environment: Ubuntu 26.04 (QEMU VM)
Trigger: Clicking either the "Voice dictation" or "Read replies aloud" buttons in the prompt area.
Symptoms: The chat layout positioning completely breaks (screenshot attached).
Workaround: Opening and closing the "Settings" window forces the chat area to redraw in the correct position.

I'm having the same issue on Arch Linux + NIRI compositor on Wayland.

The same issue also occurs on Windows 11 when using Hermes 0.18.0.
