RuntimeError: "unreachable" when rendering PDF with floating-point scale in WASM build

2. start a HTTP server

Screenshots

System (please complete the following information):

• OS: Mac
• Version 15.1
• Target WASM

Additional context
First of all, thank you for creating such an amazing project for PDF processing!

I encountered an issue and wanted to check if it might be specific to the WASM build. Here's the scenario:

I downloaded the release example and tried rendering a PDF with different scale values. However, when I use a floating-point number for the scale, I receive the following error:

(index):489 RuntimeError: unreachable

I’m not entirely sure if this issue is limited to the WASM build, but I tagged it as "WASM" for now as a starting point.

Thank you for your help!
