Bug Report: Broken section field with calc() formulas in Pro 6.8.7

Hello,

A bug has been introduced in the latest version (Pro 6.8.7).

Steps to reproduce:

Create a new section.

Edit the padding.

Unlink the 4 values.

Enter a formula for the top value such as calc(5px * 2).

Attempt to save the page: the saving process takes a very long time, and the section padding becomes corrupted after a reload.

Technical Details:

In the dev toolkit inspector, if you search for section_padding, the saved value is incorrect and contains thousands of nested calc( strings:

"calc(5px * 2) * 2 calc(5px * 2= calc(5px * 2= calc(5px * 2 calc(5px *  calc(5px * calc(5px  calc(5px calc(5p calc [cut]"

Screenshots:

This should be fixed as soon as possible.
Thank you very much.
