bug#64122: 30.0.50; The new Eglot mode line UI show too many 100% when input characters

[Eason Huang]

Hi João,

I found that Eglot mode line UI will show many 100% when using with
python-lsp-server, such as [Eglot:100%/100%/100%/100%/100%].

Is it possible to disable it and only show the [Eglot:ProjecName] in
mode-line?


steps to reproduce:

1. install python-lsp-server:
https://github.com/python-lsp/python-lsp-server
`pip install python-lsp-server`
2. Start Emacs with `emacs -Q`
3. open a python file with `C-x C-f ~/test.py`
4. start Eglot with `M-x eglot`, choose `pylsp` as the server.
5. Input some blank line the test.py buffer and you will see the issue.
In the mode line, there are always showing many 100%, such as
[Eglot:100%/100%/100%/100%/100%]

This issue also happen when using eglot on Java with Eclipse JDT
Language Server[https://github.com/eclipse/eclipse.jdt.ls]

This issue make the servers unusable on Eglot, because it will
influence the performance, and I can feel the delay when input characters.
