Thanks @xiaobaogeit ! Can you test and/or add a unit test to confirm that CesiumSomething.js does NOT match with this regex as Matt suggested in that issue?

[xiaobaogeit]

@OmarShehata I've added tests and the results are the same as expected

Thanks @xiaobaogeit .

Bumping to @mramato for final review.

Thanks @xiaobaogeit. The regex was a little loose than it should have been, since only ? or # should be the first valid character after Cesium.js. I pushed a small fix and test for this and will merge as soon as CI passes.
