Scrolling within ionic-content doesn't work with chrome devtools attached

I have a simple component with a large vertical height. This vertically scrolls happily when debugging on my attached phone unless Chrome devtools is attached. In this case scrolling is intermittent (maybe 1 in 20 attempts works). Kill devtools and it immediately starts scrolling again.

Example HTML:

<ion-content class="ion-padding" scroll="true">
<p>Content 1</p>
<p>Content 100</p>

Has anyone else experienced this? Any workarounds?
