Hi! I opened #5668 a couple of weeks ago, and this is my attempt at fixing it.
I noticed the options related to adaptive positioning were saved in a single property in the positioning service here . As a result, every time there were two components open, those options were overridden by the last one. So, my idea was to save the options separately for each component.
Any suggestions are welcome (should I add tests or demos?).
