Weird blue things appear in pdf unexpectedly

Reported by world.best.hacker.h403@gmail.com, Apr 28 2018

Issue description

UserAgent: Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.117 Safari/537.36

Steps to reproduce the problem:
1. Open some pdf
2. Double click at some word to select it
3. One millisecond before the word is selected, a two weird blue things appear near the word and disappear immediatelly

What is the expected behavior?
No weird things should appear.

What went wrong?
I don't see what is the purpose of these things to appear... Is it intended or what? If yes, I really don't see why they disappear immediatelly, so I think this is some sort of a bug.

Did this work before? N/A

wjmaclean@ looks like touch selection handles appearing and disappearing? Would this be on your side of the fence?
Re C#5, can you please provide your repro steps for Linux? I cannot unpack the rar file, nor can I get it to reproduce with the sample PDF files I've been trying.

Ok, I can repro this, but only on the first attempt after loading a pdf into a fresh tab. Subsequent double clicks fail to trigger the handles.

This seems likely a problem with initializing the TouchSelectionController ... I'll take a look.
