cpp-ladybird-refactor-variables-if-changes

CPP View before/after files on GitHub Upstream commit LadybirdBrowser-ladybird.git@a762f62 Libraries/LibWeb/Layout/SVGFormattingContext.cpp

This mapping has 86 all-to-all groups: every node on one side corresponds to every node on the other, and none is deleted or inserted. Each member carries an all N:M badge; selecting one highlights all of its counterparts, in the tree and in the code view alike.

Code view:

A painting is a person's account of this edit as text, recorded independently of the node mapping - a rendering often has several equally defensible answers where the mapping has one. Deletions and insertions carry no position on the opposite side in a painting, so that panel draws no caret for them.
