I really like using the visual editor but I have noticed that it displays SVG files at full size. This is a bit problematic because I use SVG files for my flags. When I go to edit the United Provinces the flag in the infobox scales to the default 600x300px size. I was going to go on phabricator until I noticed that the visual editor did the same thing on this page. So it seems to be universal. However, it does not do this when using visual editor on Wikipedia, for example when editing Canada on Wikipedia the flag in the infobox stays the same size as it does when viewing the page.
I asked about this on the community noticeboard to make sure I wasn't the only one experiencing this issue. Since I am not it was suggested that I bring this issue to attention here. Hopefully it isn't hard to fix.
