After the latest update today, I realized that I no longer can save, or print a page, and save it as a (any name.pdf) on Chromium Version 62.0.3202.94 (Official Build) Built on Ubuntu , running on neon 16.04 (64-bit). The file will not save If you rename it, and then try to save it. You must save it what ever name the system assigns to that pdf file, and then rename afterwards. I tested this on several computers, with the same result. Needless to say, I didn't have this issue with the previous version, as I save a lot of pages as pdf on Chromium. I tried to report this bug, but couldn't figure out what product Chromium belongs to. [bug][/bug]

Not much help I am afraid but I have just tried to download a pdf document (from http://www.pdf995.com/samples/pdf.pdf) using chromium) and it saved fine.

Using kde neon 5.11 chromium 1.1.10-2 (xenial)

Sorry chromium version is 63.0.3239.84-0ubuntu0.16.04.1 (it updated as I posted).
