** Description changed:
- Polymer v3 js library is being used for WebEngine's internal PDF viewer
- since version 5.15.2 and it is missing in the distro package
+ [Impact]
- File location in the sources:
-
src/3rdparty/chromium/third_party/polymer/v3_0/components-chromium/polymer/polymer_bundled.min.js
+ PDF files are not shown in Qt WebEngine based browsers, such as Falkon.
- Steps to reproduce the problem:
+ The bug appeared because Polymer v3 JS library, which is needed by the
+ internal PDF viewer, was excluded from the tarball for DFSG compliance.
+
+ [Test Plan]
+
1. Open a browser application based on QtWebEngine, i.e. Falkon
2. Open a PDF file either local or online. Example PDF link:
http://www.africau.edu/images/default/sample.pdf
3. See no controls and no file visible on the page, JavaScript errors on
the console
What is expected:
PDF file being opened, all controls on the page are visible, similarly to the
following screenshot

+
+ [Where problems could occur]
+
+ The fix is using a non-minified file instead of the minified one. The
+ substantial part of these files seems to be identical.
+
+ There may be still some problems with the PDF viewer, because we are
+ using a wrong file or because other files are excluded. But it should be
+ definitely better than completely broken viewer.
+
+ Also the package may FTBFS. However I tested it in a PPA and it built
+ fine on all three architectures.
+
+ [Other Info]
+
+ Please also see duplicate bug 1936821 where the same issue was reported.
