It seems to not be so much related to multiple languages, as that does work if you only add languages without a dash in them, for example nl, de works on the Windows machine here and suggests words in both languages, while en-GB, en-US doesn't suggest anything. I believe this is the issue that documents this behavior: #28684 Basically, just the English dictionaries haven't worked on Windows for the last x years, it's not related to the amount of dictionaries in the list.

The English dictionary works perfectly fine if there is not another language set:

Here are more cases:

With ['en-US', 'de']:

With ['de', 'en']:

That is very weird, if I set it to de, en in that order, I ONLY get suggestions for German, but never for English.

Does this work in Chrome/Win?

[Jelmerro]

In Chromium at least I can barely get it to work either, most of the time it doesn't even show the red lines in there, so in that respect Electron is much faster and more consistent, except that English suggestions are basically never shown. On Windows that is, other systems all work fine in both Chromium and Electron.
