<issue_to_address>
**issue (bug_risk):** `textMetaContent.Inlines.Remove(textMetaContent.Inlines.LastInline)` throws when `Meta.GetExif()` produces no displayable metadata, because `LastInline` is null. Images without EXIF metadata therefore fail while the panel is being constructed instead of simply hiding the metadata icon.
**Triggers:** When the image has no EXIF entries, or all EXIF labels or values are empty.
**Suggested fix:** Only remove the trailing newline when `textMetaContent.Inlines.LastInline` is non-null, or check whether any valid metadata was added before removing it.
```suggestion
if (textMetaContent.Inlines.LastInline != null)
textMetaContent.Inlines.Remove(textMetaContent.Inlines.LastInline);
```

Disable hit testing while the overlapping toolbar is hidden.
With HideToolbar enabled, these assignments put the caption over the preview content. The opacity trigger in QuickLook/ViewerWindow.xaml hides the caption visually but leaves its buttons hit-testable. A click near the top of the content can therefore activate an invisible toolbar button, including Close. Disable toolbar hit testing at zero opacity and restore it when the toolbar appears. WPF does not remove opacity-zero elements from input handling. (learn.microsoft.com)

Preserve FocusWindowOnOpen when showing the loading window.
When BeginLoading shows a new window, it does not apply FocusWindowOnOpen. Later, BeginShow sees IsVisible == true and skips the only Activate() call. Previews opened with this setting no longer receive the requested focus. Apply the setting when the loading window first opens. (learn.microsoft.com)

Keep the toolbar visible while the pointer is over it.
When the pointer stops over a toolbar button, the one-second timer fires and hides the caption. The timer resets only on pointer movement, and this handler no longer checks whether the pointer remains over the caption. This also conflicts with the pointer-leave behavior documented in OPTIONS.md. Keep the caption visible while it is hovered, and hide it after the pointer leaves or the applicable inactivity condition is met. (learn.microsoft.com)
