[Solved]-Bug in Highcharts after exiting the full screen mode-Highcharts

I had the same problem in higharts@8.2.2.

Reading the comment below the question, I decided to upgrade highcharts to 9.1.0.

the problem is completely solved in this version. because of the major update (8 to 9) my code confronted with few problems that can easily be handled. Hope it works for others too.

It is a controversial thing if it is a bug or not because different browsers different works in the current full-screen module implementation - you can see the whole discussion here: https://github.com/highcharts/highcharts/issues/13222

As a workaround (suggested under the above link) you can set the container height in the CSS.

Demo: https://jsfiddle.net/9b6m438y/

#container {
    height: 400px;
}
