How do I prevent matlab from preventing sleep in Windows 10 on battery?

Whenever I have Matlab open and I undock my laptop, it never goes to sleep even though my power plan should put it to sleep after 10 minutes.
When I enter powercfg -requests in the command prompt, it tells me Matlab is preventing sleep.
I have tried these two command without success:
powercfg /requestsoverride PROCESS \Device\HarddiskVolume3\MATLAB\R2018b\sys\jxbrowser-chromium\win64\chromium\jxbrowser-chromium.exe SYSTEM
powercfg /requestsoverride PROCESS jxbrowser-chromium.exe SYSTEM

This is not just a problem on Windows. I'm running 2019a on Linux (Ubuntu 18.04). For me too, jxbrowser-chromium blocks sleep. I can see evidence for this as follows:
dbus-send --print-reply --dest=org.freedesktop.PowerManagement /org/freedesktop/PowerManagement/Inhibit org.freedesktop.PowerManagement.Inhibit.GetInhibitors
method return time=1556284466.751250 sender=:1.24 -> destination=:1.3215 serial=11394 reply_serial=2
array [
string "/home/myusername/.matlab/R2019a/HtmlPanel/glnxa64/chromium/jxbrowser-chromium"
]
I thought this might be caused by the help browser, but it happens even if I haven't run help in the session.
Please fix, Mathworks!
