Affects html output

[ArmorDarks]

It seems that plugin affects html output far beyond just adding srcsets.

For instance, it changes HTML quotes:

<div class='test'></div>

to

<div class="test"></div>

Also, it affects inner whitespacing:

<div               class="test"></div>

becomes

<div class="test"></div>

While issue with whitespace doesn't seem to be serious (though, it make Git comparison show a lot of unintended changes), changes of quotes actually is a serious issue, because it will break following case:

<div data-settings='{"id":9089}'></div>

Result will be

<div data-settings="{"id":9089}"></div>

which effectively makes HTML wrong.

As expected, this is cheerio issue: cheeriojs/cheerio#1006
