\[severity:It’s more difficult to complete my work\] \[regression\] \[worked-in:18.2.2\]
I recently updated to Visual Studio 18.4.3 from 18.2.2.

In a Razor page, when assigning a property value to markup inside a `@{...}` razor code section, the syntax highlighting is treating everything in quotes as a string instead of using the C# syntax coloring rules. If the markup is NOT in a property assignment then the coloring is correct.

Here is an oversimplified example using the `Cool Slate` Theme and `Cascadia Code Semi-bold` Font. You can see that `"inputValue"` is colored correctly (white) in the first two `<InputBox>` sections, but the 3rd and 4th that are property assignments are not (redish-orange).

The correct coloring I mentioned was present in the previous versions, just after the update is it all now skewed. From some reading I have done I think it may be related to the recent change to move from the separate Razor Language Server to being integrated and cohosted with Roslyn.
