Notifications freeze when using rust-analyzer

[Andrew15-5]

I saw some notification plugins previously and was tired of comparatively ugly nvchad's LSP progress visualization. So I tried notify and fidget plugins. And they mostly are ok, but notify has a big performance problem when it comes to rust-analyzer. I'm not sure why, this is. With fidget you at least can see some progress, with notify — only the results.

When using lua-language-server both plugins perform the same. (Although in nvchad's config dir the workspace is loaded twice, idk why is that and what causes the 2 notification.)
