kie-issues#1158: On the Boxed Expression Component, changing the ExpressionVariableCell text content will fail to commit if the focus is changed to another cell

[jomarko]

Closes: apache/incubator-kie-issues#1158

In the attached screenshot we can notice:

• rectangle containing "edited name here", that has currently a focus, it is a html input element
• dark blue rectangle wrapping this input, basically a table cell

The issue is about committing the "edited name here" text using mouse click. Currently user can commit changes by clicking:

• outside whole "Invocation" expression, it means outside table
• or somewhere in dark blue rectangle but outside "edited name here" rectangle

Otherwise, the onBlur handler of the "edited name here" is not invoked. So the current draft solution is to force blur event when some table cell is clicked.

@jomarko Can you please explain this solution?

I have removed the flags, as the PR is basically done, however screenshots comparison tests are failing due to the difference of the GitHub Ubuntu machine and my local Ubuntu machine. Figuring out how to generate proper screenshots.
