This can be fixed not indenting the yanked text if it's in a comment or string.

In my opinion, this feature can be useful since some users often prefer
commands to be automated rather than having to pressing multiple keys.
This can be inconvenient in some cases, but I think it can be useful for
people who know what they're doing.

Another alternative is to create a hook for yank or that electric-indent
can also handle this.
