Explainer None Specification https://drafts.csswg.org/cssom/#dom-window-getcomputedstyle Summary When iterating over window.getComputedStyle(element) in Chromium, there is a bug where it forgets to include any custom properties set on the element. (length() on the returned object forgets to account for the number of custom properties set.) We would like to fix this bug; it brings us closer to web standards, and to Firefox and Safari, which have never had this bug. There is a performance interaction with JavaScript libraries html2canvas and html-to-image; see the document below.
