Custom meta tags not fully respected in Telegram #11233
Description
Describe the bug
Bug Description
When using the head parameter in gr.Blocks() to customize meta tags (PR #10968), the custom tags work for X and Facebook, but Telegram still shows Gradio's default meta tags instead of the custom ones.
Expected Behavior
All meta tags specified in the head parameter should completely replace Gradio's default meta tags across all platforms (including Telegram).
