Cursor v1.2 webview issue

Describe the Bug

In version v.1.2 webviews are broken. They load very slowly. This seems to be caused by an issue in version 1.99 of vscode. Check this issue webview open slow on 1.99 · Issue #245756 · microsoft/vscode · GitHub

Steps to Reproduce

Open an extension with a webview. For example the one I have made “Viz script” by fhareide. The sidebar panel will use time to open each time it’s selected. But in v1.1.7 it opens quickly after the first initialization.

Operating System
