Found some AI bugs on Windows 10 x64 on 5.70 and 5.71pre9 My automation settings are:

1: When "trim content behind automation items when editing or writing automation items" is on, automation items created by duplicate/extend right edge/ insert new item/paste do not replace the automation item like they should until they are clicked on and dragged around.

2: When writing automation onto empty envelopes in loop mode, automation items cease to record after the loopback, and do not cut off neatly at the end of the loop point. I would expect it to continue recording after the loop, making new items. When transport is paused after creating new automation items, it should glue the automation item(s) together for a seamless loop if the edges end up overlapping.

"Trim content" is also not obeyed by these duplication actions:
* "Copy selected area of items"/Paste and
* "Duplicate selected area of items".

(As mentioned in Copying and duplicating Automation items: Several bugs (and a few FRs).)
