Fix trigger node type identification on add to canvas

Editor assessment

The `fix(editor)` header is well aimed, and 'trigger node type identification on add to canvas' names the failing scenario precisely. Two blemishes: the subject starts with a capital 'Fix' where the usual style after the colon is lowercase, and the body contributes nothing but a restatement — ':bug: Fix trigger node type identification on add to canvas' repeats the header verbatim under a gitmoji. For a UI bug, a single sentence on the symptom (wrong node type detected when dropping a trigger onto the canvas) would make changelog entries self-explanatory. Header length is comfortable and no breaking-change markers are needed.
