Dear elcameno,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
It seems that I didn`t meet the same situation in my test. If it is convenient, could you share the screenshot with us.
I also would like know whether all browser have the same situation. You can try another browser to check the look of the ribbon.
What`s more, I found that quick access toolbar is not supported in Office Online. I am sorry for the inconvenience caused to you. However, thank you for pointing this out. Microsoft continuously aim to improve the features of O365 Product and suggestions like this is very much appreciated. I am also completely agree with you, in view of it will be more convenient if we can open images and PDFs in the browser. I suggest you vote this feedback: Microsoft Intune · Community. The product development team will check.
Thank you for your cooperation and understanding. Please do not hesitate to post your queries in Microsoft Community and we will always do our best to assist you!
Sincerely,
