Describe the bug
Large JSON objects cannot be validated, the following error is shown in the console when you try to do so:

wasm-0070e642-2639:10 Uncaught (in promise) RuntimeError: memory access out of bounds

Steps to reproduce the behavior:

3. Paste the contents into the JSON editor
4. Click Validate button

Additional context
I believe this is due to mono memory limits. Once dotnet/aspnetcore#5617 is fixed, then we can set a higher default memory limit in order to handle X amount of JSON in memory at a time (X TBD).
