Describe the bug
The issue is caused when a user approves a transaction in the browser extension and then uses the mobile app to speed up that transaction. The duplicate transaction does not include the input data.

To Reproduce
Step 1: On a desktop/laptop with Chrome visit https://bridge.axieinfinity.com/deposit and fill in the information for the deposit.
Step 2: Confirm in Metamask but modify the gas to be low so the transaction will not complete.
Step 3: Sync with your phone using the mobile QR code sync (Settings -> Advanced -> Sync with Mobile).
Step 4: Using Metamask mobile app speed up the transaction. The new transaction will be missing its input data.
Step 5: When the transaction completes it will send the funds directly to the contract due to the input data missing.

Expected behavior
When transactions are synced the input data should also be included so speed ups can function properly.
