Before, all `nsIContentSerializer::Append`* methods took an output string. The state of `nsPlainTextSerializer` depended on the string pointing to the same object. Now, it's ensured that the same output string is used between `nsIContentSerializer::Init` and `nsIContentSerializer::Finish`. Moreover, `nsHTMLCopyEncoder::EncodeToStringWithContext` re-used `mSerializer` without initializing it again. This was error-prone, because after serializing with `mSerializer`, it's internal state might have changed to an undesirable one (e.g. `nsPlainTextSerializer::mWrapColumn` could've been modified). Hence, it is now initialized again before serializing the common ancestors. Differential Revision: https://phabricator.services.mozilla.com/D43613 --HG-- extra : moz-landing-system : lando
