1. A concise explanation of the problem you're experiencing.
I'm using Cesium in a local application. When Chrome accesses Cesium 1.25+ on-disk (cross-origin security disabled of course), no entities will display. No errors appear on the console, instead the createGeometry worker is never requested. So far I've traced the cause to EntityCluster.prototype.update(), where none of the branches will evaluate to true.
2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.
Add a Wyoming entity to the HelloWorld app, then access the app's index.html with Google Chrome using the flags --disable-web-security --user-data-dir=/usr/USER/chrome/devprofile
3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
Attempting to use Cesium in local application that renders HTML5 GUIs with Chromium.
4. The Cesium version you're using, your operating system and browser.
Cesium 1.25 - 1.37 exhibit the bug, but Cesium 1.24 (and previous) successfully request createGeometry. Using the Chrome 60.0.3112.90 browser on Windows 7 and RHEL7.
I previously misidentified the issue as Browserify-caused, sorry about that. Feel free to close that previous thread.
