Would it make a negative impact on my research...(?)
Most/all answers say no. However in a competitive situation (be it healthy competition or nasty) it could still be brought up at some point - and when you might least expect it or be prepared to respond.
You might be giving a colloquium or a talk as part of an application for a position or funding, there will be questions, and someone may ask in a very polite way
Your results are fascinating! We can see from arXiv that your route getting there was equally fascinating, can you share some of that with us?
Have an answer in mind! Have a prepared response, so if the question ever arises, be it over tea or coffee or in a very exposed setting, you can respond without skipping a beat.
Make it an interesting story. Bring your listeners along for the ride. If it's necessary to mention a mistake, make the mistake sound interesting and delightful!
Everybody makes mistakes, but we often forget ours when thinking about others'. When you bring them along in your recounting it's more likely to remind them of their own (somewhat) similar experiences.
Do not volunteer this on your own. But have this ready if it ever does come up, no matter how likely.
...or it is normal in research?
It's not typical but what is/isn't "normal" isn't really a concern. I don't think it's a six-sigma event.
As other answers indicate, that part doesn't matter. There's no "normal" in research.
