This is a bit of a change in behaviour - I tried the SVG url demo example, and before this PR the link opens in the same window, and after it opens in a new window. Using It should definitely get a release note though, and optionally this might be a good oppurtunity to de-duplicate at least |
When embedding SVG in HTML, link `href`s can target different browsing contexts. This e.g. leads to links inside SVGs in matplotlib#31497 replacing the SVG image instead of opening a new browser window. The solution is to set `target="_blank"` for all links that implement `Artist.get_url()`. This is always intended as an external link, so universally adding `target="_blank"` is justified.

I've add a behavior change message. I'm not convinced de-duplicating the link code is worth it. Writing a function for it doesn't make it significantly shorter, and the indirection IMHO rather reduces readability. The only advantage would be easier and more consistent changes, but since I don't expect this code to be touched a lot, that doesn't weigh strongly. |

Could / should this still go into 3.11 if we make another RC? |
