[TxMt] Snippet placeholder cursor location and text transformations

I created a snippet for graphviz for subgraphs as follows:

subgraph cluster_${1/[[:alpha:]]+|( )/(?1:_:\L$0)/g} { style = filled; bgcolor = lightgrey; $0 label = "$1" }

With it in TM1, I can quickly create snippets such as: subgraph cluster_subgraph_label { style = filled; bgcolor = lightgrey;

label = "Subgraph Label" }

In TM1, after expanding the snippet, the cursor moves to the 'label = "$1"' location of the $1 placeholder. However, in TM2, the cursor jumps up to the subgraph_cluster_ line, where I'm unable to take advantage of the text transformation there. I guess this would work if reworked the transformation to be on second $1, but wanted to know what the consistent behavior is or will be.

Thank you for your help.
