Undesirable appearance when using Obsidian window frame style with High contrast light modes

[ryadaj]

When using the Obsidian frame setting for the Window frame style paired with the Minimal Theme Settings High contrast setting for Light mode background contrast and Index (round and square) for Tab style via Style Settings, there is an undesirable sharp corner at the top left, where the tab bar area meets the left sidebar.

Describe the solution you'd like

It would be great if there could be a more seamless appearance when using High contrast light modes, such as when using the Default contrast setting or Dark modes. I expect this could mean colouring the tab bar and right sidebar menu icons to match that of the left sidebar (if possible).
