I wasn't able to reproduce this issue anymore on this build https://people-mozilla.org/~schien/presentation-api/fennec-52.0a1.en-US.android-arm.apk. 
I will reopen if I will be able to reproduce again

Keep this bug open since it can still reproduced on debug build, but lower the priority because it cannot be reproduced on release build.

Bug 1697680 removed Presentation API implementation.
