Hello, JFX team!
We (at JetBrains) faced an issue with WebView after we've moved to an
JFX update in JDK8u202. The issue is that WebView stopped loading
images referenced by an absolute URL under some circumstances.
Below is a real html content, produced by IDEA markdown viewer. It has
lots of style pre-loads and a sample image that it should eventually
display. The html is loaded view WebEngine.loadContent(..) but a
placeholder text is only displayed - that's the problem that can be
reproduce with JDK8u202. However it worked with JDK8u152.
The style references will obviously fail for you, but if you put this
html into a file and will load it via
WebEngine.load(file:///path/to/file), the image will be shown with no
problem (in 8u202 as well).

Then, if you remove all the style loading and leave only the image,
the image will be shown in either way: load(url) or loadContent (in
8u202)

Sorry for not submitting the code, I hope you will easily put it into
a real demo (I played with JFX's WebViewApp).
So, could you please advice on what went wrong with it?
With regards,
Anton.
