LspStopServer only works for a few seconds, server auto-starts

[rubin55]

I sometimes work with a file where I don't want an LSP server to be enabled, maybe because I don't have a .dtd for an XML file, or maybe because I know bash_language_server will complain about a PKGBUILD but it's not helpful at that moment.

When I :LspStopServer, I see the server stopping and the highlighting stops, but a few seconds later, the server seems to start itself again. What is the point of :LspStopServer if it doesn't actually stop a server? Should I use some other command?
