Is there an estimation of when this might be looked at? It happens a lot more in our project compared to the example shown and it's confusing a lot of people here.

Turning useHTML off makes it work flawless. The issue starts with v9.2.0.

Is anyone aware of a workaround other than turning off HTML? Unfortunately we need this turned on as it is a custom tooltip

[hryhorii-kharchenko-digis]

Unfortunately, the proposed workaround of disabling "useHTML" option doesn't satisfy our goals, since we display an HTML table inside of the tooltip. We also cannot turn off "stickOnContact" option, because we use a link inside of the tooltip.

Is there any other workaround we could use?

[tsahilevi]

This makes the whole use of rich tooltips on charts unusable and a workaround of using only text isn't really a workaround...
It would be great if this can be properly prioritized and addressed. For us, we will need to evaluate our use of highcharts

Thank you for your patience! I created a draft PR but it requires some validation. Please check out the OP chart with the fix applied here: http://jsfiddle.net/highcharts/0ubatfdr/

[TorsteinHonsi]

@hryhorii-kharchenko-digis and @tsahilevi we now have something we believe will fix the issue. But to be absolutely sure, it would be great if you test it in your actual implementation. You can load https://github.highcharts.com/047bc85/highcharts.js .

[TorsteinHonsi]

Okay, since I didn't hear anything I assume it works well and merge the PR.
