Save Dialog Filter Doesn't Display All Jpeg Files

[cwmke]

Description

When saving images, already saved .jpg files are not shown by default. Only .jpeg files are visible.

Steps to Reproduce

1. Right click on an image and click 'save image as...'
2. Dialog pops up with the '*.jpeg' filter' (if the image is a .jpeg file)

Actual result:

Must switch to 'All Files' filter to view .jpg files. The same happens in reverse with saving .jpg files.

Expected result:

Whether the extension is .jpg or .jpeg, the filter should show both as they are the same type of file.

Reproduces how often:

Easily reproduced. Duckduckgo's image search is a good place to find .jpeg files. Wikipedia has some .jpg.

Reproduced on Linux and Windows (may happen on macOS too; didn't check)

If GTK (specifically, with GtkFileChooserDialog) supports multiple file extensions (like I know Win32 does, with GetSaveFileName), we could possibly patch Chromium (or fix upstream) to add custom code to look at .jpeg extensions and manually change them to *.jpg,*.jpeg, but I don't think that would be a good idea

I'm going to close this and suggest we open a bug in Chromium instead:
https://bugs.chromium.org/p/chromium/issues/list

I didn't find any existing (open or closed) issues for this in the Chromium issue log, but I suspect it would be closed as a wontfix
