Matt Key Issue - Angular 5

Question

I add a checkmark to the mat table, but I found a possible error. To play it, you must do the following:

• Click the global checkbox to select all rows

• Uncheck some checkboxes from the lines

• Check the boxes without a check box.

• Click several times in the table header to arrange the rows

• See how selected checkboxes are reset when ordering rows

The following gif shows how to play it in the following example.

• In this example you can reproduce the error

• This example does not have this error, but it is an old version of mat-table
