[Panel]: Bad spacing between arrow and title

[mhchem]

Bug Description

Looking at https://sap.github.io/ui5-webcomponents/components/Panel/, I see that the title begins with a 40px distance to the left.

.ui5-panel-header-title {
width: calc(100% - var(--_ui5-v2-8-0_panel_button_root_width));
with the variable being 2.5rem;

However, this is not according to the spec, which says B.1 = width:2.75rem (44px).

Affected Component

Panel

Expected Behaviour

2.75rem distance

Dear colleagues from @SAP/ui5-webcomponents-topic-rl ,
since this change : https://github.com/SAP/ui5-webcomponents/pull/7906/files#diff-804144e6978846de00695340bf85e6f8d23bdd59ffefd7a66e303c7b62039748
the var --_ui5_panel_button_root_width is taking its value from the base Panel-parameters, which concludes to 2.5rem, instead of 2.75rem as it is in the spec for sap_horizon theme, after the override for this theme is removed.
I hope that helps, can you, please, take a look?
Best regards,
Petya Markova.
