Operator caption is too long and overflows in the workflow editor

[chenlica]

What happened?

When an operator is given a long caption, the caption text overflows the operator's bounding box and extends well beyond it, overlapping with neighboring elements on the canvas.

Expected: the caption should fit within (or be visually constrained by) the operator — e.g. truncated with an ellipsis, wrapped to multiple lines, or otherwise capped — so it does not overlap with other elements.

Actual: the caption renders on a single line at full length and visibly extends past the operator and into adjacent operators / links.

How to reproduce?

1. Open the workflow editor.
2. Add any operator to the canvas (e.g. Scatter Matrix Chart).
3. Set the operator's caption to a long string (e.g. Compare features ababkladsfasdfkasdjf;askdfjaksl;dfasdkasdklasjdflaksdjfasdkfads).
4. Observe that the caption renders beyond the operator's bounds.
