Option to perform ALTER ONLINE is not available when we edit an existing column

[nunoperalta]

Hello,

I'm using 5.1.0, but the change made by #15312 isn't present to me.

However, the change log says:

5.1.0 (2021-02-24)
(...)
issue #15312 Added an option to perform ALTER ONLINE (ALGORITHM=INPLACE) when editing a table structure

Ah ok! I do see it, when we add a new column. Just not when we edit an existing column:

Hi @nunoperalta
Thanks for reporting this. Indeed it should be available at column edit

Hi @shucon
Would you want to do this one for QA ?

[shucon]

Sure! But I might not be able to work this week due to some unforeseen circumstances. If it's urgent feel free to take it up.

Working on it
