Tagger does not show hover text

SyntaxEditor for WPF Forum

I have several tagger that use the TaggerBase class and register with the syntax editor. The squiggles show up but when I hover, I do not see the text that I am providing. Here's my tagger.

using ActiproSoftware.Text;
using ActiproSoftware.Text.Tagging;
using ActiproSoftware.Text.Tagging.Implementation;
using ActiproSoftware.Text.Utility;
using ActiproSoftware.Windows.Controls.SyntaxEditor.IntelliPrompt.Implementation;
using Common.Analysis;
using PSScriptpad.Language;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace FormDesigner.Host.Language
class PowerShellAnalyzerTagger : TaggerBase<ISquiggleTag>
private readonly ICodeDocument document;
private PSParseData parseData;
public PowerShellAnalyzerTagger(ICodeDocument document) : base(nameof(PowerShellAnalyzerTagger), new List<Ordering>(), document)
this.document = document;
this.document.ParseDataChanged += Document_ParseDataChanged;

private void Document_ParseDataChanged(object sender, ActiproSoftware.Text.Parsing.ParseDataPropertyChangedEventArgs e)
parseData = (PSParseData)e.NewValue;
OnTagsChanged(new TagsChangedEventArgs(parseData.SnapshotRange));

public override IEnumerable<TagSnapshotRange<ISquiggleTag>> GetTags(NormalizedTextSnapshotRangeCollection snapshotRanges, object parameter)
if (document.Properties.ContainsKey("terminal")) yield break;
if (parseData == null) yield break;
if (snapshotRanges == null) yield break;
if (string.IsNullOrEmpty(parseData.Text)) yield break;

var issues = PowerShellLanguage.Instance.AnalysisService.StartAnalysis(new AnalysisRequest {
String = parseData.Text,
RequestId = Guid.NewGuid().ToString()

var snapshot = snapshotRanges.FirstOrDefault().Snapshot;

if (snapshot == null) yield break;

foreach (var issue in issues)
SquiggleTag tag = new SquiggleTag();
tag.ContentProvider = new PlainTextContentProvider(issue.Message);
tag.ClassificationType = ClassificationTypes.Comment;

var range = snapshot.PositionRangeToTextRange(new TextPositionRange(issue.Line - 1, issue.Column - 1, issue.Line - 1, snapshot.Lines[issue.Line - 1].Length - issue.Column - 1));
var textSnapshotRange = new TextSnapshotRange(snapshot, range);
yield return new TagSnapshotRange<ISquiggleTag>(textSnapshotRange, tag);

When I hover, it just shows the document's file path.

I realized I needed to register a service for this to work. 

RegisterService(new SquiggleTagQuickInfoProvider());
The latest build of this product (v24.1.2) was released 2 months ago, which was after the last post in this thread.
