[FIX] web: fix form view "More" button

In form views, when the window size is too small, a "More" button
appears and it should contain the overflow buttons.

On all browsers, the "More" dropdown doesn't contain the expected
amount of buttons, so it is shifted on the second line.

Before this commit:

    - The "More" dropdown doesn't contain the expected amount of
      buttons, so it is shifted on the second line.

After this commit:

    - The "More" dropdown contains the expected amount of buttons
      and it is not shifted on the second line anymore.
