Not sure where to post this, so within General it goes, per instructions.
I was working on Node-red, and happened to double click the HTTP Response node in my flow, and did not get an immediate response (no pun). As a typical seldomly impatient programmer, I opt to neglect how things operate and that a response takes time. That being said I double click it multiple times repeatedly... After such, I think something got piled up in the stack and came out all at once...
I've taken screen shots of the node when if finally loaded. It appears as if the node data got in a traffic jam and all piled into that node GUI all at once.... Not sure if you are able to repeat this easily. But maybe the screenshots will help clarify.
As I clicked Cancel, it seemed to process each 'instance' and gradually narrow it down to a single one...
After which seems to not really hurt the flow, as I can tell as of now. Once they were all cancelled it returned back to normal operation. I can double click into the node and have it displayed normally. As if nothing happened. No restart of node-red was performed.
