it seems that the behavior only occurs while there is already a entry defined in the array, not while it is empty
but while there is a entry defined, inserting a new line moves the table brace to my cursor and changes the indent to only use two spaces (my editor is set to use 4 spaces for indents)
inserting another new line after that will remove all indentation entirely.
here i show the brace suddenly moving upon my cursor

i expected it to simply continue adding new lines between my cursor and the brace, keeping the indentation without moving the brace relative to the cursor
i searched inside vscode’s editor settings, however i was unable to find the exact setting that could cause such a specific problem
