Development & PR Process

1. Follow MetaMask Mobile Coding Standards
2. Add release-xx label to identify the PR slated for a upcoming release (will be used in release discussion)
3. Add needs-dev-review label when work is completed
4. Add the appropiate QA label when dev review is completed
   • needs-qa: PR requires manual QA.
   • No QA/E2E only: PR does not require any manual QA effort. Prior to merging, ensure that you have successful end-to-end test runs in Bitrise.
   • Spot check on release build: PR does not require feature QA but needs non-automated verification. In the description section, provide test scenarios. Add screenshots, and or recordings of what was tested.
5. Add QA Passed label when QA has signed off (Only required if the PR was labeled with needs-qa)

Description

On signature requests whenever users tap outside the approval request remains open, this issue was fixed by #6687 and #6600. The only remaining action is to match the signature modal with the transaction modal behavior. Now, when users click outside the signature modal nothing happens as in the transaction modal.

• Consolidate behavior between signatures and transaction modals. [Bug] Signatures are not canceled and remain pending whenever tapping outside the modal, appearing later on any tx #6855 (comment)
