sometimes parallel (side-by-side) diff view is not rendering
On 8.10.5 I'm comparing two branches and I can inspect diff in the inline mode.
However clicking Side-by-side button reloads the page in the same inline view even though updated URL contains ?view=parallel
.
No errors are logged on the server side; In browser's JS console on Firefox I see the following (hopefully relevant) warning:
mutating the [[Prototype]] of an object will cause your code to run very slowly; instead create the object with the correct initial [[Prototype]] value using Object.create
that points to the following line of application.js:
function _inherits(subClass, superClass) { if (typeof superClass !== 'function' && superClass !== null) { throw new TypeError('Super expression must either be null or a function, not ' + typeof superClass); } subClass.prototype = Object.create(superClass && superClass.prototype, { constructor: { value: subClass, enumerable: false, writable: true, configurable: true } }); if (superClass) Object.setPrototypeOf ? Object.setPrototypeOf(subClass, superClass) : subClass.__proto__ = superClass; }
I'm not sure what triggers the error. Sometimes side-by-side diff works but not on the particular branch...
