   Table column visibility is saved in local storage per table. Once a user toggles any column, the saved state is used as is and the page's default visibility is no longer read.
   
   **Before**
   
   A column added after the visibility was saved is missing from the saved state, so it is shown even when the page hides it by default. For example, after a new hidden-by-default column is added to the Task Instances list, it appears for every user who had toggled a column there before.
   
   **After**
   
   The defaults are merged under the saved state. Columns missing from the saved state follow their default visibility, and columns the user toggled keep the user's choice.
