Rendering of components on Gradio versions above 5.35.0 takes too long

[Politrees]

Describe the bug

Recently, I decided to update the Gradio version in my application from 5.23 to 5.45 and encountered the problem of long rendering of pages and components. After that, I decided to check all versions from 5.23 to 5.45 and the last stable version for me was 5.35.0. Above this version, this problem appears, which greatly interferes when you need to quickly launch the interface and do your business there.

Rendering usually takes 2 to 5 seconds.

It is something in your code.

I have an advanced Gradio app which renders instantly and we are using 5.45.0.
