No highlighting for embedded js/css

[allekov]

Since micro 2.0.12 embedded js/css highlighting inside <script>/<style> blocks in html files seem broken. This is a screenshot of 2.0.11 and 2.0.12, both with default config. I also checked with 13 and 14, it's all the same.
Is this a defect or anything has changed in the default config I need to switch?

This is a regression introduced with #2810 and was not fully solved with #2840.
#3127 shall finally solve all of this, but needs a larger rework before it can be merged.
