Tables are either not displayed or are broken in the Test Description of the Test Run, when having merge cells (from the result of being made elsewhere and copy-paste into the issue)

Short Description: Tables are either not displayed or are broken in the Test Description of the Test Run, when having merge cells (from the result of being made elsewhere and copy-paste into the issue). Also, certain characters inside the table seem to break it when displayed in the Test Run, such as "\" and "|". Additionally, images inside a cell are not displayed with the borders of the cell and overlap it.

Steps to Reproduce:

1 - In the Excel or Word, create a Table and merge some of those cells.

2 - Create a Test and copy-paste this Table to the Test Issue description.

3 - Create a Test Run and navigate to it.

Actual Results: The table is not displayed at all.

Expected Results: The table should be displayed.

4 - Write anything inside the Table (in the Test Description of the Test issue itself) and navigate to the Test Run.

Actual Results: Nothing of what it is writing inside that table is displayed because the table has merged cells.

5 - Now, create a table in Jira and paste an image inside of one of the cells and also insert the character | in the content.

Actual Results: In the Test Run, the image is not displayed inside the cell borders and the table gets broken when using certain characters.
