ToolTip cuts off text if font size is changed with styles

[Angelore]

Describe the bug

If the font size for TextBlock is changed in the parent container, ToolTip cuts off the last word of the string.

The issue goes away if the string is changed in very minor ways, such as adding spaces or removing a colon:

To Reproduce

Set the font size to 16 and create a tooltip with the following text: Injectable: Monster in the Drain

public string OriginNameFormatted => "Injectable: Monster in the Drain";

  <Grid.Styles>
    <Style Selector="TextBlock">
      <Setter Property="FontSize" Value="16" />
    </Style>
  </Grid.Styles>
  <Panel VerticalAlignment="Center" HorizontalAlignment="Center">
    <PathIcon Data="{StaticResource Icon}" ToolTip.Tip="{Binding OriginNameFormatted}"/>
  </Panel>
</Grid>

Expected behavior

I expect the ToolTip to adapt to FontSize changes, and either display the full string, or to wrap it.

I have tried targeting tooltip directly, and the result is the same.

<Grid>
  <Grid.Styles>
    <Style Selector="ToolTip /template/ ContentPresenter#PART_ContentPresenter">
      <Setter Property="FontSize" Value="16" />
    </Style>
  </Grid.Styles>
  <Panel VerticalAlignment="Center" HorizontalAlignment="Center">
    <PathIcon Data="{StaticResource Icon}" ToolTip.Tip="{Binding OriginNameFormatted}"/>
  </Panel>
</Grid>

Since ToolTip default still is limited in width, to avoid extra-long tooltips, it should wrap.

Note that there has been a text measurement issue since the 11.0 last previews that causes this same issue in appearance. It's probably the same overall.

In that issue color name tooltips in the ColorPicker are cut off in exactly the same way. It's always been reproducible with the ControlCatalog.

If it isn't an issue with text measurement / DPI / Display Scaling, it may be another popup lifecycle issue. I have long thought styles aren't evaluated correctly when popups are opened and there are other open issues for that.

I don't think this is a beginner issue to fix.

Edit: If it's a Popup style application issue here is where it was last discussed on my end: #14145 (comment)

#17875 (comment) could you give that PR a try? I know it's focused on Runs but maybe it helps anyways?

Looks like it was tested by a gentleman in that issue.
