This issue has been verified using Visual Studio 17.13 Preview 1(9.0.10 & 9.0.0 & 8.0.100). Can repro this issue on iOS platform.

Maybe this can be fixed with the workaround mentioned in #17757 as this worked for me for a very similiar freezing issue (mark bigger chunks of text fast).

I can confirm that the work-around fixes the issue - thanks @formerlymisterhenson :)
