I am using the Sitecore 8.2
I have a template T1 which has rendering R1 set on its Standard Values (set a long time ago, maybe at the age of Sitecore 7 or earlier).
There is a set of templates T2, T3, etc. which inherit presentation details from the T1 standard values + each of them has some additional renderings assigned to their Standard Values.
I noticed that if I update a placeholder name of R1 on the T1 standard values, it is not populated to the rest of the inherited templates.
Is that an expected behavior?
What would be your suggestion on updating all of the template's placeholders for R1?
