focus link space

Hi,
When a link is focused (clicked before), the space before and after is removed.
Like: …this is some textlinkmore text after link…
If the link is not focus, the space are displayed correctly.
I have seen this issue is some webs that I use this plugin.
Of course if I disable the cache, the issue disappears.

You know some fix??

Thanks!
