I currently developing an installable WebApp (PWA) and found an issuse with the Indexed DB API.

Issue: QuotaExceededError on 50MB throughput/limit when PWA is installed
After "add to homescreen" install of the WebApp I cant store more than 50 MB in IndexedDB. 
I try to store recordings (~10MB ArrayBuffer) in Indexed DB to upload this data later.
And I only save the data temporaly in indexed db, after an upload process the data gets removed. 
After about 50MB throughput the API throws an QuotaExceededError when I try to store more data. 
Because I deleted the data first, I would expect that I can store data again. 
Also this hard limit is only there when I install the PWA. When I use the browser this limit is not there and it works like expected.
