Log Message:

[UnifiedPDF] Crash in UnifiedPDFPlugin::repaintForIncrementalLoad() loading
charbonnelchocolates.com page
https://bugs.webkit.org/show_bug.cgi?id=274563
rdar://128316806
Reviewed by Abrar Rahman Protyasha.
repaintForIncrementalLoad() can get called before the main thread has a
PDFDocument or has created any layers,
so early return in that case. This web page has a `display:none` iframe with
PDF contents, which triggered
this crash.
