Dealing with selection when collapsing a tree node

I am building a software which has a tree structure filter. Selecting a node from the tree loads information about it in a table on the right.

What do you believe is the best option for node selection when the user clicks on an ARROW next to a node (just the arrow).

Version 1 - the node collapses, the node which arrow the user has clicked gets selected

Version 2 - the node collapses - no new selections - the table on the right still displays the previously selected nodes' information.

What do you guys think? Thank you in advance
