Popover and Popover arrow position, width and direction issues inside a table

[StallionV]

• I have searched the issues of this repository and believe that this is not a duplicate.

Reproduction link

Steps to reproduce

1. Create a table
2. Ensure have a column which has a link or a button which can show a pop over
3. Add a ConfigProvider to ensure popover scrolls with the rows
4. Toggle the Ellipsis prop for column and see how the pop over width and position is affected. The popover is actually getting rendered inside the column.
5. In some cases when there is not enough space to render pop over in its present direction, the direction changes but the popover arrow still points to the original direction not the new one
6. Toggle the placement prop for popover, if you don't add it we notice the popover width is correct. Adding it somehow limits the width and sometimes also changes the popover direction
7. Popover randomly changes direction showing a flick affect on screen. If first shows at one position and then switches quickly and shows at another making it appear like a glitch

What is expected?

1. Playing with ellipsis prop in table or placement in popover, should not affected the popover so dramatically.
2. Pop over arrow direction should show correctly in accordance with popover direction
3. Before rendering pop over, if it is determined that the space may not be enough and the popover has to instead show up in a new place, do not render it twice. It shows popover at one place and then flicking to another.
4. Pop over width should not change if placement prop is provided

What is actually happening?

1. Playing with ellipsis prop in table or placement in popover, affects the popover. Ellipsis prop for table makes popover render inside the column, specially when it has a ConfigProvider
2. Pop over arrow direction changes randomly sometimes, if popover direction changes
3. When changes direction, pop over seems to render twice in some cases and so makes it appear like a glitch or flicker affect
4. Pop over should width change in some cases if placement prop is provided

For expect.1, it's by design. Table ellipsis use html native ability which makes container as overflow:hidden. So if config getPopupContainer to parentNode, it cut as expect.

For placement dynamic change arrow not switch is a bug. I will take a look.

Thanks @zombieJ how about points 3 and 4.
Why does the width of pop over change and why does it render twice. I believe those are also bugs
