Inlay hints are shown only in an active window if more than one window displays different areas of the same buffer

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

If I have two frames, or two windows in one frame, displaying different parts of the same Rust code buffer, inlay hints are displayed only in the active window/frame. If the windows/frames display the same region of the buffer, then both of them display the hints.

See the included screenshots.

Steps to reproduce

• Open path.rs from the Rust standard library, or any other large Rust source file
• Move to a position where inlay hints are shown
• Open another frame displaying the same buffer
• Move to another position where different inlay hints are shown

Expected behavior

Inlay hints are shown also in the window/frame that is not active.
