Bug: Chat doesn't render when auto_insert_mode is set true until mode is switched to normal

[abhr-0]

There seems to be a bit of rendering issue when the chat buffer is opened in insert mode using the auto_insert_mode option.

From what I can tell, currently rendering is triggered on the events TextChanged and InsertLeave only, and so the render doesn't happen until leaving insert mode.

I may be missing something or may have misconfigured something, can anyone else reproduce this behavior?

Adding InsertEnter to the autocmd when auto_insert_mode is enabled seems to fix the issue locally, and I'd be happy to open a PR if this approach is acceptable.

I was able to reproduce this on a completely clean config, with just lazy.nvim and CopilotChat.nvim.
Everything set to default except the auto_insert_mode option.
