Memory leak when using mouse scroll

[cehteh]

Thank you for the bug report

• I am using the latest version of lsp-mode related packages.
• I checked FAQ and Troubleshooting sections
• You may also try reproduce the issue using clean environment using the following command: M-x lsp-start-plain

Bug description

When scrolling down with the mouse wheel, CPU usage goes to 100% and memory usage dramatically increases until it hits OOM pretty fast.

I originally reported that at rustic: emacs-rustic/rustic#60

Steps to reproduce

1. Load rust source file.
2. Enable lsp-mode (rustic here) with inlay hints and lsp-update-inlay-hints-on-scroll enabled.
3. Scroll to the bottom of the file.

Expected behavior

No busy loop/not OOM

Which Language Server did you use?

rust-analyzer

OS

Linux

Error callstack

no callstack, but profiler output which helped me to isolate the problem:
