Resizable panel constraint handling: Disabled resizing unexpectedly collapses the panel · case 04
Disabled resizing unexpectedly collapses the panel.
Case contract
Disabled handles preserve size; trailing-axis handles reverse delta; add deltas to current size and clamp to min/max.
Why this case matters
A deterministic model of resizable panel constraint handling; this isolates one interface invariant without requiring a browser.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| disabled | 20 | 50 | Failed |
