Annotations disappear shortly after adding

[ctron]

Description:

I have a language server, which provides problem diagnostics. It works in VScode. But with this project, I can see the annotations for a brief moment, before they disappear again. However, this doesn't happen all the time, but in like 95% of the cases.

The file on which this happens (Maven POM file) does have another annotations too. I created a "test annotator", just to verify that this isn't a problem. Those annotations do survive, so I expect the issue is with lsp4intellij.

Steps to reproduce:

Hard to tell. I don't have an easy reproducer.

Affected Versions:

0.95.0 and 0.95.1

I dug a bit deeper and what happens is that the code ends up here:

lsp4intellij/src/main/java/org/wso2/lsp4intellij/contributors/annotator/LSPAnnotator.java

Lines 78 to 81 in daaa032

	// If the diagnostics list is locked, we need to skip annotating the file.
	if (!(eventManager.isDiagnosticSyncRequired() || eventManager.isCodeActionSyncRequired())) {
	return null;
	}

I am not sure I do understand the whole processing, but it looks like there is some weird state issue going on.
