Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
HTML Format Document no longer formats with embedded JavaScript and CSS blocks.
Since Cursor 3.10.10
Example:
< !doctype html >
< html >
< body >
< script >
function test() {
console.log(“hello”);
}
< /script >
< style >
.foo {
color:red;
}
< /style >
< /body >
< /html >
Expected:
The formatter should indent JS and CSS inside the HTML tags.
Actual:
Format Document does nothing for embedded < script > and < style > content.
Note: a HTML file without embedded script or style tag does format, so do separate JS files or CSS files
Regression:
Working:
- Cursor 3.9.16
- Cursor 3.9.8
- Cursor 3.7.19
- Cursor 3.6.21
Broken:
- Cursor 3.10.10
- Cursor 3.10.11
- Cursor 3.10.17
The latest VS Code and Windsurf still format the same file correctly.
Steps to Reproduce
Create a rudimentary HTML file (make sure language mode is on HTML)
Insert a script tag with a simple js piece and do the same for a style tag (see example html above).
Now right click in the document and choose “Format Document”
Nothing happens
Expected Behavior
The formatter should indent JS and CSS inside the HTML tags.
