Getting "/deep/ combinator is deprecated" Warning Today

Hello,

So in one of my Qt projects we use QWebEngine and this has been working as it should for many months now. This morning the application began to no longer function when we launched our web pages through QWebEngine, instead giving us a warning in the console logger stating:

/deep/ combinator is deprecated. See https://www.chromestatus.com/features/6750456638341120 for more details.

Did some searching and read the information in the link, but still unclear why this is just happening now unless they finally removed something this weekend. Anyone else getting a similar problem or know what the solution is?

Looks like we had some internal network issues causing the fault on this.
