When copying the HTML code of a website into a test.html in phpstorm, there are some questionable warnings, especially, when it comes to SVG, like:
- "feDropShadow" HtmlTag not known
- "width" and "Height" attribute are according to phpstorm - not allowed on a <symbol> tag (But.... they actually are, see link below):
It does NOT complain, when:
- a symbol has a "xmlns" attr (which is not listed as allowed not core attr in -> see link below)
Maybe there are even more...
What is going on here? Is phpStorm responsible for validating? Or is it an external library?
Should really be fixed...
