Canvas syntax highlighting not syncing with theme changes via GPThemes btn

[itsmartashub]

The CodeMirror editor in the canvas feature fails to properly update its syntax highlighting when themes are changed using the GPThemes floating button. While the overall UI theme changes, the code highlighting remains in the previous theme's style, creating a visual inconsistency.
But if we refresh the page, everything is great. Tho, I want to avoid the need of page refreshing on every theme changes.

However, changing the theme via the ChatGPT settings correctly updates the CM syntax highlighting.

Manually changing the theme value in localStorage updates the syntax correctly.
