Browser support for `std/hash`

I am trying to call createHash() from a bundled library loaded in a web browser, but the bundled JavaScript file has to compile WASM that the browser reports is too big for the main thread:

Uncaught RangeError: WebAssembly.Compile is disallowed on the main thread, if the buffer size is larger than 4KB. Use WebAssembly.compile, or compile on a worker thread. at issue.bundle.js:253

Description of demo files attached in WebAssembly.Compile_issue.zip:

• issue.ts:

import { createHash } from "https://deno.land/std@0.106.0/hash/mod.ts";

const hash = createHash("sha256");
hash.update("Some data to be hashed");
console.log(hash.toString());

• issue.bundle.js: Generated via deno bundle issue.ts issue.bundle.js. The line 253 of concern is

const wasmModule = new WebAssembly.Module(decode("AGFzbQEAAAAB   [...]

• issue.html: Imports the JS bundle via <script type="module" src="issue.bundle.js"></script>

Serving and browsing to issue.html results in the above error regarding WebAssembly.Compile.

If I’m expecting too much of the bundler here, what’s the simplest workaround to be able to call createHash() from a library loaded in a browser? Thank you.

This issue should probably be closed. std/hash has been removed from std.
