Send Value is Appending Value two times intermittently on iOS 13.X Device

Description

We have observed issue with Send Keys while typing the value in the Text Field on iOS 13.x Device. The same value is getting appended twice intermittently on the iOS Device.

I have analyzed the logs and observed that Java Client is calling Send Keys WDA API twice and value is getting appended.

Please find the attached logs and reference below for calling setvalue method in WDA two times.

Code To Reproduce Issue [ Good To Have ]

Please remember: it's easier to reproduce and fix the bug with sample code.
You can git clone https://github.com/appium/appium/tree/master/sample-code or https://github.com/appium/appium/tree/master/sample-code/apps and reproduce an issue using Java and sample apps.
Also you can create a gist with pasted java code sample or put it here using markdown. About markdown please read Mastering markdown and
Writing on GitHub

Exception Stacktraces

Please create a gist with the pasted stacktrace of the exception thrown by java.

Link To Appium Logs

Please create a gist which is a paste of your full Appium logs, and link them here. Do not paste your full Appium logs here, as it will make this issue very long and hard to read!
If you are reporting a bug, always include Appium logs as linked gists! It helps to define the problem correctly and clearly.

Start by reproducing the issue with Java Client 7.0.0 on a real iOS 13.2 or 13.3 device, using the Appium logs in the report to verify the request sequence. Trace the send-keys path that invokes the WDA setValue endpoint and confirm completion when one client action no longer causes the value to be appended twice.
