According to the MDN compatibility data, see https://developer.mozilla.org/en-US/docs/Web/API/DOMMatrix/DOMMatrix#browser_compatibility, all browsers that we support have native
DOMMatrix
implementations (since quite some time too).Hence Node.js is the only environment that lack
DOMMatrix
support, which probably isn't that surprising given that it's browser functionality.While the
DOMMatrix
polyfill isn't that large, it nonetheless seems completely unnecessary to bundle it in thelegacy
builds when it's not needed in browsers. However, we can avoid that by simply listingdommatrix
as a dependency for thepdfjs-dist
library.
