Issue Summary

Issue descriptions containing tables with merged cells are not retrievable using the REST API.

Steps to Reproduce

1. In a spreadsheet such as Excel or Google sheets, copy a range of singular (non-merged) cells.
2. Past the cells into an issue description and validate that the table renders correctly.
3. Query the REST API with https://sometenant.atlassian.net/rest/api/2/issue/\{issueKey}?expand=renderedFields
4. In a spreadsheet such as Excel or Google sheets, merge two cells together and copy a range of cells including the merged cells.
5. Past the cells into an issue description and validate that the table renders correctly.
6. Query the REST API with https://sometenant.atlassian.net/rest/api/2/issue/\{issueKey}?expand=renderedFields

Expected Results

At steps 3 and 6, the value of the description field accurately reflect the table in the issue description.

Actual Results

At step 3, the value of the description field accurately reflect the table in the issue description.

At step 6, the value of the description field shows <!-- ADF macro (type = 'table') --> in place of the table.
