[css-gaps-1] Bikeshedding names for ways to break gap decorations

[kbabbitt]

Authors may want one of several different behaviors for drawing gap decorations in a Grid that contains spanning items. The spec defines the column-rule-break and row-rule-break properties (and shorthand gap-rule-break) to select between these behaviors, with one of three values. (In the examples below, I've also set gap-rule-outset to 0 to emphasize the difference between them.)

They might want decorations to stop at each intersection:

gap-rule-break: intersection;
gap-rule-outset: 0px;

Or at each T intersection:

gap-rule-break: spanning-item;
gap-rule-outset: 0px;

Or only at the edges of the container:

gap-rule-break: none;

Questions:
1. Are there suggestions for better names for these values?
2. Currently in the spec, the initial value selects the "T intersection" behavior. Is that what most authors would expect as a default?
