Data corrupted for Table, version - 10.2

Hello Team,

We will be upgrading from existing "10.0.20" to "10.2.14-MariaDB-log" on Production running on linux.

But before this I was testing "10.2.14-MariaDB-log" on my local machine on Windows and I came across a use case which includes adding 2 columns (With new feature of default value as SQL expressions) and 1 check constraint including those two new columns, on a table consists of only 1 dummy record.

And soon after that when I dropped those 2 columns along with constraint, I mistakenly misspelled constraint name, which results in the 1 record of table become corrupt.

So please find attached the exact commands which caused by 1 record of my table become corrupt and kindly confirm the bug.
