  • introduce safelySetHref and change all elem.href setters to use it. it ensures we don't set a link to a javascript:evil() url.
  • add safelySetBlobHref. same kinda idea.
  • remove the bag of attrs method signature from createElement. it opens another vector towards accidentally setting href/src/etc to something bad. it was unlikely, but that syntactic sugar didn't really save us much. :)

wow, dom.js in here. I even thought it looked "pretty handy" to have in here in the original review :)

I feel like it shouldn't be crossing out of the report anymore. Since it's equivalent to document.createElement() calls now, do you mind cutting out dom.js now?


beforeAll(async () => {
assert = (await import('assert')).strict;
jsdom = await import('jsdom');
pageFunctions = (await import('../../lib/page-functions.js')).default;
DOM = (await import('../../../report/renderer/dom.js')).DOM;
