Trim time Bars moves Keyframes

when I use “[” to trim one or multiples time bars, the keys in it will stretch and move to accomodate the new lenght.
same if adding/removing a new segment. which render the tool pretty frustrating to use.

It is possible to extend the bars by hand. this way it doesnt move the keyframes in it. However, it is not possible to add/remove a segment without loosing the position of the keyframes.

I a not sure if this is intended ( and i am missing an informations )or a bug.
but a workaround would be lovely.


PS: notch version :
