another case: code completion get even worse for a long enum name. See this video: https://cln.sh/R5VqSTCq

Another case： ObjC Enum： XXImagePreviewVideoStateNormal use xximprvist show the candidates, but if I continue write no (xximprvistno), the result shows empty.

Another case: File: XYCommonBase/Build Keyword: XYComBa/build Actually result: shows nothing expect: shows the file as result. Please fix.

I am pretty sure that this issue persist on the 15.2 released version. If you set photo permission to PHAuthorizationStatusDenied in Settings, and call registerChangeObserver: without check the permission (to do a alert or something), the App will stuck 20s. Is there some workarounds for the old version of our apps?
