Describe the bug

As soon as I edit anything in the Rich Editor any table column alignment is removed.

To Reproduce

Go to

CMS Demo

Switch to Markdown and enter:

Table:

| Left | Center | Right |
|------|:------:|------:|
| L1   | C1     | R1    |
| L123 | C123   | R123  |

Switch to Rich Editor:

=> Preview is correct.

• Type anything, anywhere, even outside of the table

=> Preview changes and all table cells are left-aligned.

Switch to Markdown:

Table is now:

| Left | Center | Right |
| ---- | ------ | ----- |
| L1   | C1     | R1    |
| L123 | C123   | R123  |

Expected behavior

Editing the document in the Rich Editor should not change the table's columns' alignments.
