WIP: target legacy browsers #49

This should make it work in older browsers (WebViews) by polyfilling (and maybe something else?) the features that are used in the code, but are not supported by older browsers, like optional chaining.

I haven't actually tested it on such older browsers.

See webxdc/checklist#22

TODO:

• As @adb tested, this makes is stop working (white screen).

Debugging tip on Desktop:

(削除) place a breakpoint on fill_up_connections
in webxdc-wrapper.html, step into then reset numIterations to 0
after the numIterations = 50 line has been executed (削除ここまで)

In dev tools, select the index.html context and execute location.reload().

the .browserlistrc file is missing, check the file from the checklist repo.

would be great if you make this work!

@adbenitez @WofWca what is blocking/missing to get this in?

once this is merged, we should also do a new release

could you rebase this, and please in general spend a bit more effort describing in the PR main description the issue being addressed, and how? By linking to a discusssion in some other thread you are off-loading this interpretation work to all readers.

I rebased it and updated the description.

i ran "npm run build" and then put the resulting dist-release/editor.xdc (195K instead of 151K) into a chat -- but starting yields an empty screen. Does this basic test work for you?

but starting yields an empty screen

Precisely. It doesn't work for me either. This is why the MR is marked as WIP.

Closing this PR because it's factually stale. Can we revived if needed.
