I have the same issue with develop branch in the product page.


Thanks!

Hi,

In the product page, if we click on the help icon button, they are not well-displayed and they are superposed.

Thanks!

@matks is it a critical task for 1.7.6 ?
We need to prioritize this issue compared to all the other projects in progress.

@colinegin It looks really dirty in the BO now and popups are messed up. Looks critical to me and I think @marionf will agree ^^

[marionf]

Yes and furthermore it's a regression

[khouloudbelguith]

In the product page, we have other issues.

After

Thanks!
