fix: color picker dialog hex field value not setting correctly

[geronimol]

Description

Currently, when you pick a color from the toolbar(either font or background color), the hex field in the color picker value has always the same value. This fix will make the field display the current value.

Thank you for the contribution, your branch is outdated, could you rebase to fix the CI failure? Also, a CHANGELOG.md change is needed to document your fix.
