Research direction

The payload names no files or tests, so start by reproducing: open a long Java file in Zed with this extension, make edits, and check whether highlights and parameter inlay hints drift further down the file, as the screenshots show. The reporter says a save refreshes the positions, so compare the positions the language server sends after an edit with the ones Zed renders. Done means the offset stops appearing after edits without a save, with a reproduction and a note on whether the cause is in the extension, Zed, or JDTLS.

Description

I don't know if this is a bug with the extension, Zed or JDTLS, but it has been happening for months so I figured I might as well report it and hopefully one of you guys here can find where the actual issue is.

Like the issue title says, there is a disconnect between the positions where highlights and inlay hints should be in the code and where Zed displays them.

Here is a screenshot of the parameter name inlay hints to show what I mean:

And what it should look like:

And here for highlights (I have the cursor inside lastName here):

I haven't figured out what it is that triggers this; it just happens every now and then when I edit the code in a file. It also does not happen across the entire file; it starts at some point and then gradually gets worse the further down the file I go from there. If I make any change to the file and save it, the LSP will refresh the information and everything ends up in the right spot again (i.e. the offset issue disappears).

This is quite annoying, although not vital since it disappears after doing an edit and saving.
