PCB editor: Changes made in Pad Connections trough edit footprint don't survive "Update PCB from schematic".
<!-- --------Before Creating a New Issue-----------
* Limit report to a single issue.
* Search the issue tracker to verify the issue has not already been reported.
* Complete all instructions between `template comment markers <>.
* Keep report contents limited to the necessary information required to fix the issue.
* When creating an issue against the stable version of KiCad, make sure the latest available stable version is installed as issues may have already been resolved in later stable versions. -->
# Description
<!-- What is the current behavior and what is the expected behavior? -->
<!-- If the issue is visual/graphical, please attach screenshots of the problem. -->
<!-- Add the issue details below this line and before the "Steps to reproduce" heading. -->
Local changes to "Pad Connections" on PCB seem to revert themself. I would expect them to persist until I update footprint from library.
# Steps to reproduce
<!-- If there are multiple steps to reproduce it or it is a visual issue, then providing a screen recording as an attachment to this report is recommended. -->
<!-- If this issue is specific to a project, please attach the necessary files to this issue. -->
<!-- Add the steps to reproduce using the numbers below -->
<!-- Add new step numbers before the "KiCad Version" heading. -->
1. Create project with connected circuitry and a footprint, for example Button_Switch_SMD:SW_SPST_TL3305A
2. Create PCB normally from schematic.
3. Edit footprint on board. Go into properties - select "All pads with duplicate numbers are jumpers". Ratsnest between internally connected pads should disappear.
4. Execute "Update PCB from schematic". Ratsnest between pads 1-1 and 2-2 will reappear.
# KiCad Version
<!-- Copy version information (from main menu Help->About KiCad ->Copy Version Info) and paste it between the triple backticks below to preserve the formatting. -->
