This is not related to editing. It's a general issue with selectability of counters in generated ::before/::after. Also, it looks like it's only a paint artifact.

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/9d8a90f8a7f49c673bcd4e369efc84c62cc18285 commit 9d8a90f8a7f49c673bcd4e369efc84c62cc18285 Author: rune <rune@opera.com> Date: Mon May 08 21:54:23 2017 Counters are always generated content and cannot be selected. Copying selection across generated ::before/::after with counter() did not copy the contents, but the counter content was painted as selected as if it was. LayoutTextFragment was already overriding the implementation of CanBeSelectionLeaf() to skip generated content, but LayoutCounter inherits from LayoutText which returns always true. Return false for LayoutCounter as it is always generated content.
