+- When using `clojure` with `clojure-lsp` `lsp-mode` is interfering with typing (e. g. deleting whitespace while typing), how to fix that?
+    - The issue is caused by `clojure-lsp` server being more aggressive with formatting(deleting whitespaces) and `aggressive-indent-mode` being on and calling it while typing. The solution is either to disable `aggressive-indent-mode` or to disable `lsp-mode` formatting via `lsp-enable-indentation`.
