Missing operator delete/delete[] for some allocated objects

Hi.

Looks like there are few places in the Terminal code where I can suspect a memory leaks due to missing operator delete or operator delete[].
These allocation sites can be grouped into following:

• raw operator new without operator delete like this https://github.com/Microsoft/Terminal/blob/master/src/cascadia/TerminalConnection/ConptyConnection.cpp#L191
• allocation by operator new some global object or class member (https://github.com/Microsoft/Terminal/blob/master/src/cascadia/TerminalControl/TermControl.cpp#L281)
• allocation by operator new some memory in a function and return it by raw pointer, which can leak then.

Here is my gist with quite a simple grep foroperator new calls - https://gist.github.com/dreamer-dead/c43248466fc4d445378b4dfba80d8d25

Is this an intentional behaviour or a bug that should be fixed?

Review the allocation sites identified in ConptyConnection.cpp around line 191 and TermControl.cpp around line 281, then compare them with the linked grep results. Determine whether each raw allocation has an appropriate owner and matching deletion, and whether the behavior is intentional. Done means documenting the conclusion or addressing confirmed leaks across the listed sites.
