[Mac] Instructions Documentation page becomes broken after clicking the Print icon

Describe the bug
When viewing an introduction documentation page on macOS, clicking the Print icon causes the page to break. The page does not recover unless it is manually refreshed.

Steps to reproduce the behavior:

1. Navigate to https://makecode.microbit.org/beta on macOS.
2. Scroll down and select any project card that includes a Show Instructions button.
3. Click Show Instructions.
4. On the opened documentation page (for example, the Wallet project at https://makecode.microbit.org/projects/wallet).
5. Click the Print icon and observe the documentation page.

Actual behavior
After clicking the Print icon, the documentation page layout becomes broken and does not display correctly until the page is refreshed on Mac platform.

Expected behavior
The documentation page should remain intact and display normally after clicking the Print icon, without requiring a page refresh on Mac platform.
