Unkown element svg:foreignObject

Please could you share a file/complete code snippet the issue can be reproduced with?

https://stackblitz.com/edit/angular-7pxzuc?file=src%2Fapp%2Fitem%2Fitem.component.html

it works fine for me if the code is enclosed in

<svg xmlns:svg="http://www.w3.org/2000/svg"></svg>

and doesn't work otherwise

please follow https://youtrack.jetbrains.com/issue/WEB-45385 for updates

Hi, Elena. The similar issue with `markerUnits`, `patternUnits`, `patternContentUnits` attributes.

<svg:marker
    xmlns:svg="http://www.w3.org/2000/svg"
    markerUnits="userSpaceOnUse"
    viewBox="0 0 10 10"
/>

<svg:pattern
    xmlns:svg="http://www.w3.org/2000/svg"
    patternContentUnits="userSpaceOnUse"
    patternUnits="userSpaceOnUse"
/>

But it works fine without namespace.

`Ctrl + Click` on CSS class name and class name auto-completing don't work if svg element has a namespace prefix.

Thank you, Elena. What is about auto-completing and navigating to CSS class names by `Ctrl + Click`?
