A concurrency control error occurred within model

Hello,
I’m facing error "A concurrency control error occurred within model “aa0573b2-9d81-43de-9865-f567b135116a” when internet is disconnected and connected again.

Here consider tab 1 & tab 2 as participant 1 & participant 2
Here are the steps to regenerate the issue -

  1. Open ace editor same example on 2 browser tabs.

  2. Disconnect the internet

  3. After the internet lost type the below code at line no.2 in tab 1
    This is first tab
    This is the first tab contents

  4. Type the below code at line no.2 in tab 2
    This is second tab
    This is the second tab contents

After inserting above code connect the internet again.

Then you will see the tab 1 contents as -

Error message in tab 1 console -

The model with id ‘aa0573b2-9d81-43de-9865-f567b135116a’ was forcefully closed by the server: invalid reference event

Tab 2nd content as -

Error message in the tab 2 console -

ERROR 18:48:02.512 A concurrency control error occurred within model “aa0573b2-9d81-43de-9865-f567b135116a”.
Error: Acknowledgement did not meet expected context version of 360: 362

After that If I type something in tab 1 or tab 2, it doesn’t get reflected in other tabs.
