This is accomplished by changing the property set to this:\n *\n * --foo_-_border: 2px solid red;\n * --foo_-_color: initial;\n * --foo_-_background: initial;\n *\n * This works but introduces one new issue.\n * Consider this setup at the point where the `@apply` is used:\n *\n * background: orange;\n * `@apply` --foo;\n *\n * In this case the background will be unset (initial) rather than the desired\n * `orange`. We address this by altering the property set to use a fallback\n * value like this:\n *\n * color: var(--foo_-_color);\n * background: var(--foo_-_background, orange);\n * border: var(--foo_-_border);\n *\n * Note that the default is retained in the property set and the `background` is\n * the desired `orange`. This leads us to a limitation.\n *\n * Limitation 1:\n\n * Only properties in the rule where the `@apply`\n * is used are considered as default values.\n * If another rule matches the element and sets `background` with\n * less specificity than the rule in which `@apply` appears,\n * the `background` will not be set.\n *\n * Limitation 2:\n *\n * When using Polymer's `updateStyles` api, new properties may not be set for\n * `@apply` properties.\n\n*/\n\n'use strict';\n\nimport {forEachRule, processVariableAndFallback, rulesForStyle, toCssText, gatherStyleText} from
