#8528 Added default Icon column

Editor assessment

The subject opens with the bare ticket number '#8528' between the prefix and the description, violating the placement rule that the summary start immediately after the colon-space; the content — a default icon column is added — follows behind the junk. The fix type fits a default-value correction. The body's squash bullets name the control type and the test update, giving modest implementation context. No malformed footers appear. Understandable after skipping the junk, but the placement flaw and thin rationale hold the message at acceptable.
