UITableViewCell not clipping to borders during extension animation

I am trying to implement a fairly simple tabular view with an expanding cell containing a UIDatePicker, with autoplay / freemasonry cells and auto-sized.

I have a problem with the expanding date picker cell. When the cell containing the date picker starts to expand, its content appears outside the cell, although I have clipsToBounds = YES

both for the cell itself and for the cell.contentView. I also tried reinstalling clipsToBounds = YES

after layoutSubviews

.

Sorry for the quality, but here is a gif showing the problem of animation in slow motion.

Any ideas on how I can store the date picker in my cell? Any help would be greatly appreciated!

Perhaps the relevant code snippets:

Insert / Delete

[self.tableView beginUpdates];

if (showingStartTimePicker) {
    [sections[TableSectionTimes] insertObject:@(TableRowStartTimePicker) atIndex:index];
    [self.tableView insertRowsAtIndexPaths:@[[NSIndexPath indexPathForRow:index inSection:TableSectionTimes]] withRowAnimation:UITableViewRowAnimationTop];
} else {
    [sections[TableSectionTimes] removeObject:@(TableRowStartTimePicker)];
    [self.tableView deleteRowsAtIndexPaths:@[[NSIndexPath indexPathForRow:index inSection:TableSectionTimes]] withRowAnimation:UITableViewRowAnimationTop];
}

[self.tableView endUpdates];

      

        
        
        
      

    

DatePickerCell

- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {

        [self setClipsToBounds:YES];
        [self.contentView setClipsToBounds:YES];

        _picker = [UIDatePicker new];
        [self.contentView addSubview:_picker];
        [_picker makeConstraints:^(MASConstraintMaker *make) {
            make.edges.equalTo(self.contentView);
        }];
    }
    return self;
}
