Win10 & Win11 both. Recent occurrence, likely a recent update.

That right-click context menu is displayed because you're right-clicking the image itself, not the HTML that embedded the image.

Images can be copied, saved, opened in a new tab, etc. But the image is not HTML -- there's no "source" associated with the image itself.

If you're looking for the HTML source code that includes the URL of the image (e.g. so that you can embed the image in an FR comment), you have to right-click on the text of the article/page that the image is on.

Then you will see "View Source", and you can search in the source HTML for the reference to the image, which will typically be something like:

<IMG SRC="https://some_website.com/some_path/image.jpg">

There may be additional elements after the SRC string and before the closing angle bracket, such as:

WIDTH="600"

If you want to post an image that is very large, it is good to use the WIDTH element and set a value less than 1000. There's no need to explicitly add a HEIGHT element, since modern browsers will automatically scale the HEIGHT of the image so that the displayed aspect ratio stays the same as the original.
