* Add explicit loose configuration for babel private-property plugin
Squelch this warning that happens a few dozen times during CI by
following the instructions:
Though the "loose" option was set to "false" in your @babel/preset-env config, it will not be used for @babel/plugin-proposal-private-property-in-object since the "loose" mode option was set to "true" for @babel/plugin-proposal-private-methods.
The "loose" option must be the same for @babel/plugin-proposal-class-properties, @babel/plugin-proposal-private-methods and @babel/plugin-proposal-private-property-in-object (when they are enabled): you can silence this warning by explicitly adding
["@babel/plugin-proposal-private-property-in-object", { "loose": true }]
to the "plugins" section of your Babel config.
* Use spaces instead of tabs
This won't affect the test.
* Make all the other "implied loose" options loose, too.
This now squelches the warnings, and webpacker can compile without failing.
* Collect common option "loose: true" to preset env
Rather than 3 overrides to bring these inline, move to the shared options.
* Revert "Collect common option "loose: true" to preset env"
This reverts commit ca3d09ba6a47e03dbfb5f6108fcbc7f19b5a457b.
