You cannot do this without updating all references to TotalHeigh In Arduino_Core_STM32
Eg it is defined as
uint32_t TotalHeigh; /*!< configures the total height.
In Arduino_Core_STM32

Marlin will not compile with this change when this code is included.

well wait, you pointed main branch but we are not on it...
1.9 is closer to codeql branch (legacy branch)
https://github.com/stm32duino/Arduino_Core_STM32/blob/codeql/system/Drivers/STM32H7xx_HAL_Driver/Inc/stm32h7xx_hal_ltdc.h#L146

nevermind, i linked bad line/var.. https://github.com/stm32duino/Arduino_Core_STM32/blob/codeql/system/Drivers/STM32H7xx_HAL_Driver/Inc/stm32h7xx_hal_ltdc.h#L103 yea :p

Test procedure. Set the following
platfomio.ini
default_envs = BTT_SKR_SE_BX

Configuration.h
#define SERIAL_PORT -1
#define MOTHERBOARD BOARD_BTT_SKR_SE_BX
#define BIQU_BX_TFT70
#define TFT_CLASSIC_UI

Applying this PR results in this error.

This was "fixed" once before in #22531 and I reverrted it in #22776.

Perhaps we need comments on these types of variables to prevent them from being caught up in spell check PRs.

[thisiskeithb]

default_envs = BTT_SKR_SE_BX

We also have a standard BX config now, so perhaps our CI test should be updated (it would have caught this).

@thisiskeithb looking at luzpaz GitHub, this seems to be a mostly automated system for finding spelling errors in code.
So comments may not help, but a CI test will stop this occurring again...

I'll submit typo fixes to the upstream repo: https://github.com/stm32duino/Arduino_Core_STM32.git
There are so many typos in the source (currently at 723 files and still not done)
