Taking a snapshot of a non-trivial sized game has an unusably low resolution

[mconnew]

Describe the bug When taking a snapshot of a game on the Blocks page by right clicking and choosing "Snapshot", if the game is larger than a trivial demo, the resolution of the downloaded image is too low to be usable. I tried multiple games and the dimensions of the downloaded image does increase slightly with larger games, but not by much (1300px wide vs 1100px).

To Reproduce Steps to reproduce the behavior:

1. Go to https://arcade.makecode.com/S96303-09966-16248-41620
2. Click on 'Edit Code'
3. Right click on editor background and select Snapshot
4. Open downloaded snapshot in image viewer/editor

Expected behavior An image of the blocks which is of sufficient resolution to be suitable for copying pieces out to use in instructions for children

Screenshots I've cropped the image down as there's no need to upload the entire image. This has not been scaled, simply cropped.

Desktop (please complete the following information):

• OS: Windows 11
• Browser: Firefox, but also reproducible in Edge
• Version: 122.0 (Edge version was 121.0.2277.83)
