Chrome Version: 72.0.3596.0 (Official Build) canary (64-bit)
OS: macOS 10.14.1 18B75

When a download is in progress and you try to close the last tab, Chrome warns that it’s about to quit, and implies that quitting Chrome will cancel the download. In reality, on macOS, closing the last tab does not quit the browser.

What steps will reproduce the problem?
(1) Close all windows. Open a single tab and begin a download. Download something large enough that it’ll take enough time to complete step 2. https://dl.google.com/chrome/mac/stable/GGRO/GoogleChrome.dmg, sadly currently 70MB, is a pretty good choice.
(2) Once the download begins (it’ll show up in the download shelf), close the tab.

What is the expected result?
On macOS, the tab should close without incident. The download continues in the background because Chrome is still open. Closing the last open window does not quit Chrome on macOS.

What happens instead?
An alert appears:

 --
| Download is in progress
| Quit Chrome anyway?
| [[Continue Downloading]] [Quit]
 --

See the attached image.

This is a recent regression. I’m tentatively setting this as M72 because it’s recent, but if it turns out to have regressed in M71, this bug should be retargeted.
