For example: ``` <base href="/modules/" /> <script type="module"> import './module.js'; </script> ``` should load `/modules/module.js` and not `/module.js`. 1569957 1 guybedford 2019-09-11 11:55:32 -0700 Correction: the problem is specifically for dynamic imports: ``` <base href="/modules/" /> <script type="module"> import('./module.js'); </script> ``` where the top-level parent for the dynamic import should still respect the base. 1570817 2 webkit-bug-importer 2019-09-13 20:23:26 -0700 <rdar://problem/55361194> 1662929 3 ysuzuki 2020-06-15 18:22:52 -0700 The problem is that import is using SourceOrigin information. We should add a flag to that like, "this source is inlined script etc.".
