Bug 1966220 [wpt PR 52510] - [soft navs] Add smoke test for DOM modification support.,
Automatic update from web-platform-tests [soft navs] Add smoke test for DOM modification support. For now, this tests that we support Element.innerHTML, Node.appendChild, and Node.insertBefore, Document.importNode, Document.adoptNode, and template element. This isn't a fix for the bug mentioned here, but hopefully some baby steps towards it. :-) Bug: 328783345 Change-Id: I4be5de236acc8cf7da37a665b26c77f6f7f218ef Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/6532832 Commit-Queue: Johannes Henkel <[email protected]> Reviewed-by: Michal Mocny <[email protected]> Cr-Commit-Position: refs/heads/main@{#1459667} -- wpt-commits: af1e34f8e178a17780fa230b01f4ecc13a83f107 wpt-pr: 52510 Differential Revision: https://phabricator.services.mozilla.com/D250158
