Added CSS style not disappearing on reload in Chrome developer tools

Question

I am working on some front end design, and while fiddling with some stuff in Chrome developer tools I added the following to the webpage I am working on:

Even after reloading (and emptying cache and hard reloading) this style persists, regardless of whether or not I have the developer tools open.

I am not sure where this style is coming from or why it refuses to quit!

Has anyone experience something similar and were able to figure out a solution?

EDIT: If it matters this is being applied to a table element

Answer 1

Only two options really: either you defined the width: 100% as an inline style or it's being added via JS as an inline style.
