Capture, bubble, and the order people forget to write down
Capture and bubble sound like classroom words until two squads share a status page. One squad attaches a resize handler on the way down. Another attaches on the way up. A third, older handler lives on the window because a chart library registered it in a year nobody in the room still occupies. The panel that “should” have the last word does not.
We drew that grid for an adult education provider after an inventory showed three resize handlers on a panel the product counterpart thought was quiet. The inventory was the catalogue. The flagship sitting, later, wrote the order. One handler set a height; another, firing later, set it again; the chart’s listener then measured a box that no longer matched the layout the first squad had intended.
People forget to write the order down because each handler is reasonable in isolation. The map is reasonable only as a sequence. If your brief is “the panel jumps,” do not ask us only whether a listener exists. Ask us in what order it fires, and on which trip — capture or bubble — it gets a vote. That sentence is the difference between an inventory and an activity analysis.
