Specification None Summary Report a predictable storage quota from StorageManager's estimate API for sites that do not have unlimited storage permissions. It is possible to detect a user's browsing mode via the reported storage quota because the storage space made available is significantly smaller in incognito mode than in regular mode. This is a mitigation that prevents detection of a user's browsing mode via the storage API by reporting an artificial quota, equal to usage + 10 Gib, in all browsing modes for sites with limited storage permissions. Sites with unlimited storage permissions will be unaffected. Enforced quota will also be unaffected.

Please list open issues (eg links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (eg, changing to naming or structure of the API in a non-backward-compatible way).
