pyodide crash on a formula that works with gvisor

[mmaura]

Describe the current behavior

I use a modified version of the substitution by templates (https://support.getgrist.com/examples/2023-07-proposals-contracts/).
I added a function to get the days and months in French in the substitution of template. After adding this function (with the sandbox pyodide) it becomes impossible to add columns to any table, the error message appears :

error [pyodide error] RangeError: Maximum call stack size exceeded at wasm://wasm/02239a6e:wasm-function[3174]:0x25deab at wasm://wasm/02239a6e:wasm-function[3175]:0x26a9f5 at wasm://wasm/02239a6e:wasm-function[1045]:0x1asm9was/029/01a60/0wasm-function[2490]:0x1fdbb7 at wasm://wasm/02239a6e:wasm-function[2114]:0x1e4dbd at wasm://wasm/02239a6e:wasm-function[3174]:0x26719b at wasm://wasm/02239a6e:wasm-function[3175]:0x26a9m/15 wasm5

If I change the sandbox to gvisor, then the document works correctly.
