In release mode, the "minification" of shell.html remove spaces that should not be removed

[ypujante]

Please include the following in your bug report:

Version of emscripten/emsdk:
3.1.61

I have a custom shell.html that I provide to emcc via the --shell-file= option.

When I do a build in release mode (with optimizations), shell.html gets minified.

Here is an excerpt:

As you can see all the spaces BEFORE and AFTER all anchor tags are removed which makes the rendering wrong and TBH quite unreadable...

The tool we use to minify HTML is html-minifier-terser, called from here:

emscripten/tools/link.py

Perhaps adjusting the flags there can fix this? Or perhaps this is a bug in that project?
