It depends on the person inspecting the passport. There are no specific common laws or rules that say that big ink spills are bad, but small ink marks are fine. Even some official stamps may sometimes get recognized as "a damage".
I personally would not bother. It's hard to notice, it does not obstruct any text, chip, visas or stamps, it does not look like a stamp or a text, and it does not look like a tampering, at least to me personally. I would not consider the passport damaged, and I would not expect more problems than usual.
However, I don't visit any countries that are known to be notoriously strict for passports like mine. If I'm to visit, I wouldn't be surprised if such mark is used as a formal cause to deny entry, should the officer want to. Of course, if there are no marks, there are plethora of other causes to deny entry.
Also, I wouldn't recommend trying to remove the mark yourself or with someone else's help; now that's something that may look like tampering.

Is it considered damaged?
No.
Will I have any issues ?
No.
Passports are "working document". Mine have been scribbled on, stickered in, bend, folded, smudged, dog-eared, etc. Immigration officers aren't exactly "gentle", so some amount of wear and tear is fully expected.
