Since the edited website pages are inside an iframe, the options panel
cannot base its display on the CSS rules of the page. When changing the
theme colors, only the edited page's CSS is reloaded, not the option
one. Because of this, the background shapes are displayed using an
obsolete color palette inside the options panel.
This causes colors to be forced on background shapes within the iframe
because their default colors do not match the ones inside the options
panel when different theme colors are set. Once forced, the colors of
the background shapes within the content do not follow the theme
palette changes anymore.
This commit forces the background shapes displayed in the options panel
to use the current palette.
This is done by recovering the current edited page's shape background
images from the CSS rules. This approach was chosen as opposed to
adding a `d-none` version of the shape `div` to the edited page and
getting the background image from its computed style.
This fixes the color comparison between the background shapes of the
content and the ones of the options panel, thus not forcing colors if
the theme colors are used.
Steps to reproduce:
- Edit a website page.
- Drop a "Banner" block.
- Enable background shapes.
- Go to the theme tab.
- Select a different theme color palette.
- Select the "Banner" block.
- Open the "Shape" option's menu.
=> The shapes were displayed with the old color palette and if selected
were applied with the old color palette.
Additionally, to avoid a race condition when leaving a theme color
picker by either clicking on the BLOCKS tab or re-selecting the
snippet with a shape, a re-rendering of the existing snippet editors
is requested and the shape cache is invalidated if the palette has
changed in the meantime.
