Inserting a date into the first cell of the first column in a table prevents the selection of other cells in the same column, this issue happens only in Firefox, other browsers are not affected like Chrome, IE, Safari.

Environment

• Confluence 6.15.6
• Firefox 68.0 (64-bit) on Windows

Steps to Reproduce

1. Create a table
2. Add a date using // in the first cell of the first column
3. now all the other cells in the first column are not selectable

Expected Results

User should be able to select all cells in the first column no matter what data is inserted in the header.

Actual Results

User can't select any cells in the first column by mouse clicking

Notes

• Viewing the source-code of the page, shows contenteditable parameter for <time> tag which is the date value in the first cell is set to "false"
• setting the value of the parameter to "true" makes the cells selectable in Firefox
