Export: Empty odd pages

[MrVitaly]

Versions

• Fast report version: Demos/FastReportWebCore.MVC fom the sources as is (Latest commit 664c4e9)
• Browser version: Google Chrome v. 70.0.3538.102 (64-bit), IE 11.407.17134.0, MS Edge 42.17134.1.0

What happened

Printed documents contain extra empty odd pages with note "Generated by Fast Report.Net" only.
For example: when I want to print the demo report "Simple list" which contains 3 pages, I get printed 7 pages when pages 2, 4, 6 contain required content and extra empty pages 1, 3, 5, 7.

Steps to Reproduce

Steps to reproduce the behavior:

1. Run project "Demos/FastReportWebCore.MVC.csproj";
2. Select "Simple list" demo report;
3. Press "Print from browser" button;
4. See printed pages.

Expected behavior

Printed document should contains 3 pages with required content only.
