Description

• This PR fixes bug. The loading bar in 'metadata-create' reappears when hitting 'back' button in chrome. This is solved by removing bgcache (back-forward cache) in firefox. (I did not know this was a thing)

@philter87 Are we worried that when googling 'unload event' the developer.mozilla website states that it should no longer be used, should there be a note about it being deprecated, or are they referring to something different?

Nice catch! I will investigate a bit more. It might be a problem

@K-Beicher. You are right, that it is not an optimal solution, but I am unable to find a better solution for clearing the bfcache in Firefox. I have found a long discussion about it here but it seems that there is no simple way to opt-out of the bfcache, yet.

But there could be another solution. Maybe we can remove the page in the browser history as returning to it might cause some weird behaviour - like uploading the columns twice

@lwjohnst86 is it possible to make an issue that will appear in a years time to revisit this and see if a solution has shown up?
