// ES2018, but Firefox fails to implement it. There has been an open issue
|
|
// for this (see https://bugzilla.mozilla.org/show_bug.cgi?id=1362154) since
|
|
// 2016 now, and Mozilla fails to fix this. To avoid breaking support with

// Firefox, we explicitly disable the ESLint rule here and use a regular

|
// expression without a named capture group. We should check from time to
|
|
// time, whether support in Firefox has finally been added. Besides the
