I am also having this issue. It seems to happen most when I focus the URL bar, and the dropdown appears with suggestions, however it is not 100% reproducible.

Unable to reproduce the issue on mac 10.13.3 using chrome reported version #67.0.3396.62 and latest canary #69.0.3448.0.

Attached a screen cast for reference.

Following are the steps followed to reproduce the issue.
------------
1. Selected part of a url in the omnibar.
2. Pasted the url in a new tab.
3. Observed that the selected text is pasted as expected.

vhosune@ - Could you please check the issue on latest canary #69.0.3448.0 by creating a new profile without any apps and extensions and please let us know if the issue still persist or not.

Thanks...!!
