Describe the bug In dark mode text on shapes with light background is unreadable while editing even when explicitly set to black and is not always readable before or after editing.

To Reproduce prerequisites: dark mode is on

Steps to reproduce the behavior:

• drop archimate rectangular 'business actor' shape on canvas (actually any shape with light solid fill will do, not necessarily from the standard library) - default font is white on light yellow and therefore unreadable
• go to text pane and select black font colour - text becomes black and readable
• press F2 to edit the text and type something - text again becomes unreadable while typing, typing blind
• while still in the text field change font colour to black - it becomes red!
• click elsewhere to exit - black text that looked white becomes black, but black text that looked red becomes invisible - not even white

Expected behavior In all steps all text should've been black

draw.io version (In the Help->About menu of the draw.io editor):

• draw.io version 26.2.2

Desktop (please complete the following information):

• OS: Windows 10

** Additional context

Also note that throughout the whole process the business actor icon in the top right corner remained light and unreadable even though it should've been black from the very start.
